He meant the first thing.
He only ever directly ruled one land: Israel.
He imposed a law on Israel, intending for it to make Israel prosperous.
He's God and he knew that he was doing.
It was this:
(1) Free land distribution at the beginning, with it automatically reverting to the original family after a number of years (and no way to contract out of that.
(2) Debt elimination, by law, in the seventh year. People have to be able to repay the debts in six years. If they can't, then in the seventh year the debt is erased and the people go free of it, with no residual owed. This was MANDATORY for Israelites and any foreigner who sojourned with them in Israel. If Congress passed a law that automatically and without recourse cancelled every private debt every seven years, we would (rightly) say that was government action. In Israel, the government enforced this - by not permitting debt collection in and after the seventh year. There was no opt out for normal people.
(3) Mandatory lending to poor people who asked. The rich did not have the power to refuse to lend to the poor Israelites who asked. They could neither hoard money, nor choose to refuse to lend. Think about what that meant for capital formation. It meant that the the rich had a strong incentive to lend out all of their excess capital voluntarily, to people they choose (poor family members, neighbors and friends), because if they weren't spontaneously generous with loans - to people they knew whom they figured would pay them back - then poor people they DIDN'T know and couldn't trust could ask them for a loan, and they did not have the legal right to refuse. God's law was mandatory, and it effectively forced those with wealth to put all of their accumulating capital back into circulation and not attempt to hold it - for the law then granted the poor the right to ask for a loan, and denied the rich the power to refuse it.
So, the "voluntary" aspect for the rich was merely whom they decided to lend it to FIRST, BEFORE somebody else asked to borrow it. If the rich sat on their wealth and didn't voluntarily choose to lend it out to neighbors and friends in need, then the law forced them to lend it out to the first people who asked.
And the law forced the lender to forgive the unpaid debt after seven years.
(4) And what of the bankrupt in, say, the second year who could not pay his debt? The lender had this option, if he was a fellow believer: he could simply let the man go to try to pay him back, and forgive the portion unpaid in the seventh, Sabbatical year. Or he could go to court and the man would be directed into the lender's service to pay for the debt. Now, note well: the Hebrew could not be ENSLAVED by the lender. He was an indentured servant. He, and if he had wife and choldren, they had to be clothed, fed, housed, provided for AND PAID, though that pay could be withheld until the end of the term. The support could not be. If the lender could not provide for the bankrupt, he could not take him into forced service.
Then, when the sabbatical year came, the 7th year (not of the debt, but the official seventh year), whatever was unpaid on the loan was wiped out, and the indentured man was free to go. And the lender had to pay him wages for his work to send him on his way. He could not send him out empty handed.
(5) Interest could not be charged on lent money to the fellow Hebrews.
None of these laws were voluntary, or goodness of the heart thing. The rich HAD TO LEND, if asked, and HAD TO FORGIVE in the Sabbatical Year. And the conditionas of indenture were set and had to be respected.
(6) Going further, even foreign slaves had to be freed in the 50th year, the Jubilee.
(7) Land ownership was absolute, in the sence that in the 50th Year it ALWAYS reverted to the orignal title family. Nothing could stop this - not debt, not criminal punishment, not the desire of some generation to not be in that land. There was a minimum level of family land protection below which the law did not let anybody fall. No matter how badly a generation squandered everything, the next generation would get the land back, for free, and could start anew as farmers, in their tents, on their own land, which could not be taken for debt or punishment or taxes.
(8) The use of the land, however, was not absolute. The farmer had certain, but not absolute, rights to his crops. Notably, the farmer could not prevent the poor from passing through his fields and orchards and picking what they needed to eat. The poor could not take baskets and take food away, but they could always walk through and feed themselves directly by plucking fruit off the trees or grain heads and eating them there. The poor did not need to pay for the fruit. This was not a privilege, this was a legal right.
(8B) Also, the farmer, in harvesting his crops, was allowed a pass through with his workers. They were not, however, permitted to go back through and harvest the late blooming food, nor to go back and pick up anything they dropped. These gleanings were legally the property of the poor - the poor had the right to come on the land and pick all of these things and take them, again for free. The farmer was not permitted to harvest right to the edge of his fields either, that was to be left as gleanings for the poor.
(8C) Every 7th year, and also in the 50th year, the farmer was not permitted to either plant crops nor harvest what grew of its own accord. This was all left as gleanings for the poor.
If you've ever been to California, you have have seen vast orange and grapefruit groves with huge numbers of oranges and grapefruit fallen from the trees sitting on the groud, and big signs warning that picking up fallen fruit is theft, and entering the orchards is tresspassing.
Under God's law, the orange farmers have no right to do any of that. Poor people have the right to walk through the orchard and eat that fruit.
The economic theory is simple and especially spoken of by Jesus: man is not an owner of wealth. He is a steward. All wealth comes from and belongs to God, and God has directed, by law (enforceable in the courts of ancient Israel), certain things to be done with his property: mandatory lending without interest, mandatory debt forgiveness, mandatory right to eat from the fields, mandatory gleanings. These aren't just good ideas or suggestions from God - they are God's mandatory charity, and were intended for the good of all, that there not be any hunger or true poverty in the land over time.
Our belief and argument is that wealth is the actual PROPERTY of the wealthy man, to do as he pleases.. This is not God's law at all.
None of these laws have been incorporated into our laws.
And finally we have (9), the law of mandatory tithes for the poor and for support of the Levites. There were other taxes, such as first fruits and the priest's portions of each sacrifice, but the tithe was earmarked for support of the Levites and for them to distribute to the poor. Nothing about this was voluntary.
Now then, one could correctly note: "We are not under the law, that was just for Israel", and that's true - but only to a point. We are not under THAT law, exactly, but we ARE under the Law of Jesus, and HE gave the direct (and ugly for the stingy) parable of the sheep and the goats, with those who who said "Where did we see you hungry and not feed you?" etc., being sent into the fire. So yes, it's true, we are free from having to structure it exactly as God did (although if we think we're wiser than he we are as stupid as we are arrogant), but no , we are not free to simply not have a structure: the penalty for not getting the job done is hellfire, and truth is, before we set up universal public education we had broad ignorance, and before we set up Social Security we had a great deal of destitution among the old and poor: the system of private charty did not get the job done, which is why we moved back towards the government structures of modern time, which parallel the government structures God set up in Israel.
American conservatives hate all of this, but it's right there in the Torah, and in Jesus' own law.
that he get off twitter 
and learn and practice Rom 12:21 Do not be overcome by evil, but overcome evil with good.
