If opposite was true then there would be never debate about helping bankers after crisis few years back, government shouldn't have power to "help" private investors with taxpayers' money.
> If you concentrate more and more wealth in fewer hands, then you can also expect corruption.
Why should I care about corruption inside companies? Corrupted companies are less effective, they will eventually die. What I care about is corruption inside government - you have no solution for corrupted officials - I have: just don't give them too much power, then even if they are corrupted they won't make much damage.
> The thing about capitalism is that capital generates capital. Someone who is already wealthy can "chill" and get a better outcome than someone who works much harder.
That's not the feature of capitalism, that's feature of corrupted government with too much power - in free market, if you have capital and don't create any goods, but only spend it eventually you have less capital - it's simple math.
