I just reread my post, and noticed that I wrote the first sentence completely wrong. It's too late to edit, so here is what I meant to say:
Inequality does not come from capitalism. Liberty allows inequality. Those "negative outcomes" come from inequality, not capitalism. Fighting capitalism (socialism) is a workaround. It's an appealing workaround because the "underlying system" is centralized, and inequality is not.
The negative effects of inequality are free to do harm in a society with capitalism. That does not make capitalism the cause of those effects, it simply means that capitalism does nothing to prevent them.
Socialism does (claims to) do some things to fight inequality, but that does not mean I must prefer it to capitalism.
