Because at some points, it starts becoming unfair.

When there are no more hungry, unhealthy citizens, then it's unfair. When there's a system designed to educate and heal, designed to turn the unfortunate into the privileged, then it'll be unfair.
And the best thing is, when the investment in a system like that bears fruit, when future muggers and drug addicts are turned into future doctors and engineers, they'll all be paying tons of taxes.
