Absolute rubbish.
There is nothing corrupt about maximizing profits as long as participants are free to accept or reject any offers.
Capitalism is the only system where all participants, ie. investors, employees, customers, and suppliers are 100% free.
Under any form of socialism people are forced with the threat of violence to comply with mandates they may or may not agree with.
There is nothing evil about maximizing profits... except the fact that profits don't exist in a vacuum, and must come
at the expense of someone or something else. Education. Freedom. Safety. Ethnic groups. And so on.
To ignore that would be economically irresponsible.
And, you may still be missing the point. I am not saying g Capitalism can't work. In fact, our ignorance of our own evil makes capitalism so easy to work. I am saying capitalism works, and works best with corrupt leadership. As said before, from a mathematical standpoint capitalism maximizes profits, which means there is a local minimum of profits for someone. Very basic.
The problem with capitalism is that there is no incentive to HELP, especially in such a greed driven type of economy. No one in a capitalist society will, or should make an investment without expecting more of a return than the principle put in - plus dividends. Capitalism is only about CAPITAL. It is as far from social interaction through love and care as possible; capital is the point.
Socialism demands a perfect leader at the very least so as not to corrupt the government with lopsided pleasantries only for the leader. This may be shocking, but HEAVEN will NOT be capitalist; it will be more socialist than anything. That is because the currency in heaven is love, devotion, friendship and gratitude. You won't find heavenly entities trying to sell a piece of their spirit for a few intergalactic coins. You won't find angels complaining that they saved a planet, but only received a macaroni picture in return. Things are done out of love, not profit, in an ideal socialist society.
That is the difference: ideal capitalism needs ideal corruption (like today

ideal socialism needs an ideal leader.
No one is free in the Ponzi of capitalism. It is based on usury, debt, poverty and economic subjugation in exchange for more monopoly fiat money. Capitalism with or without a perfect leader is an atrocity to the character of humanity (of course, those who profit from capitalism see it as shining and a beacon.)
It isn't rubbish just because you say it is.
