I would argue that capitalism, far more than any other economic system, rewards intellectual capability.
Which certainly provides the opportunities for the disabled to achieve things they wouldn’t otherwise be capable of elsewhere.
Can you measure how capitalist countries give the most to charity, by far, in financial terms?
And how to explain this phenomenon? Is it that human nature is not to be measured by the cold curve of supply and demand, and that the broad accumulation of wealth afforded capitalist societies might actually prove to be of tremendous humanitarian value?
Or are we just here to bash capitalism in favor of insert non-existent liberal utopia here?
No, but the idea of Capitalism was founded on real-world observations that, when people were given incentives to work hard in pursuit of the common good, that they did so. And when they weren’t, they were lazy, selfish bastards.
Capitalism is, in effect, charity. It’s a motivational system towards a charitable lifestyle.
