Capitalism is simply the natural way of people owning and choosing how to buy and sell what they own without force. Each individual makes decisions and bears the responsibility for those decisions, and freely decides how best to make use of what he has.
It is not a system at all in the end, it is the natural way of doing things. Every child understands it. One person owns one thing, another owns another and they decide between each other how to exchange it without interference by busybodies.
This results in lack of waste and invention, entrepreneurship, innovation… people owning their own businesses and taking responsibility for what they truly have responsibility for rather than relying on a mafia of so-called government officials.
Captalism is ultimately simply natural freedom.

And so naturally it does well.
Communism and Socialism are imposed systems, artificial creations, based fundamentally and simply on some people with guns telling you to give them all you own, so they can decide what’s best supposedly according to made up rubrics, supposedly to distribute it to ‘the people’.
A convenient excuse that
does not justify theft, and is an unnatural construction placed over human society. It gives the people in charge of distribution
the power, and corrupt people gravitate to it who do not work – and they create class warfare to perpetuate it – in other words an unnatural hate and envy between people with more material goods and those with less.
It is in other words, based in the sin of envy and perpetuated by it and other sins, such as laziness, self-righteousness and pride where people think they know better than others how to use material goods, and so forth.
It is no wonder that it never works and always causes waste, corruption, devaluation of human rights and destruction of the work ethic.
Its errors are what Our Lady of Fatima warned about coming out of Russia and perverting human society.
