Not arguing with you, but what would you replace it with or specifically how could we tweak it to make it more Christian?
Are you familiar with Distributism as promoted by G.K. Chesterton, Hilaire Belloc, and Fr. Vincent McNabb? You can read about it here:
Utopia
This is one of many fine articles at this website. The principles of Distributism are free enterprise, individual liberty, private property ownership, and smallness instead of gigantism (i.e. small privately-owned businesses instead of giant corporations).
Capitalism is opposed to all these and is very anti-individual. Try talking about free enterprise to someone who owns his own business and is deluged with regulations by government pests who couldn't run an ant farm successfully. We have no individual liberty. As for private property - the banks own everything through the use of the unbiblical means of usury. Capitalism benefits an extremely small segment of society - the uber rich who own the banks. It is highly individualistic, meaning that it opposes the community regulating the behavior of businesses in favor of draconian state rule. An example of this would be when police are sent to natural farms selling produce, vitamins, or raw milk, and with force close these private businesses down because those giant corporations whose profit margins are being ruined don't like it
You are given the illusion of being free under Capitalism. You aren't. Want to see how "free" you really are? Try missing a few payments on your house or car. You are OWNED. Your whole life is expected to work for the good of about 25 giant mega-corporations who run most of the world, and the banks who support them. You are expected to go along with the system, and if you don't, you will be trashed. It is not coincidence that four countries that threw out the international banking cartels were invaded and their leaders killed. This is why Colonel Gaddafi was offed by the U.S. Government. He dared to oppose the international banking cartel and set up his own gold-based economy based on the dinar.
There's so much more. Do some research. You may be shocked and appalled at what you find. The one good thing about the Internet is that these scoundrels no longer can hide behind their lies. What we, the people, are going to do about it, remains to be seen.
