(1) Imagine harder.
Get personal experience or talk to someone with personal experience with WIC, food stamps, disability, medicare/medicaid, etc. and you'll find out how inefficient, wasteful, and abused these things are. And I don't just mean by a little bit. I mean by A LOT.
(2) I agree that collective agencies can be more effective than individuals.
But not the government kind that are (a) awfully inefficient and (b) exact their contributions by force. I donate a significant portion of my income voluntarily to organizations of my choice that do good in better ways than writing legally mandated entitlement checks.
