Capitalism instead made food absurdly abundant and gave everyone air conditioned boxes.
Edit: to address all of the nonsense responses below all at once: China's embrace of capitalism has lifted hundreds of millions of people out of poverty.
Capitalism didn't give us shit. We had to trade 1/3 of our lives for that "abundance". Don't make money because you're disabled? Doesn't seem so abundant anymore. Also, growing food isn't a byproduct of capitalism. The agricultural revolution began before capitalism existed. Imagine how much better your life would be if you didn't parrot ruling class talking points. You aren't ruling class so stop LARPing as a member of it.
