Those people exist among us and they're called homeless people.

But less glibly, I bet you would find many such people in this thread.

To fix the problem of capitalism, you would have to fix the problem of pricing (=efficient allocation of) goods into supply chains, which problem grows as the fourth power of the number of goods available.

It's probably better to keep making our current system more transparent and work for prices to better reflect society's values than to "exit capitalism".
