Capitalism is not a lie, only that what the world has today in industrialized nations being referred to as capitalism when it is not.
What the world has are mixed economies, mixed socialist-capitalist economies, closer to what might be considered fascist states.
Still on the spectrum the US and most commonwealth nations are more capitalist than the others, with some respect for individualism, private capital, and mutual beneficial trade allowed.
It is the socialist nations that believe there are winners and losers in any transaction. Capitalist minded nations believe there are win-win transactions, both parties get what they want, what they trade for, to better each.
More capitalism the better. Let’s watch Argentina for now as it goes down the path towards capitalism.
