Exactly as I see it. And ending welfare enables us to end a whole host of other government problems.
For example, end welfare and people will be more liable to pick wise career choices instead of the ones government pushes us to (i.e. college oriented "careers" many of which don't work out well).
End welfare and people are more liable to not do drugs to begin with. (Look at how little drug abuse there was before the welfare state -- because people would see the few people in the gutter and not want to wind up like them).
End welfare and people will eventually go back to saving for their future like the greatest generation did -- less need for government "help" for senior citizens.
End welfare for farms (the farm subsidies that pay farmers to not grow food, ideally to prevent a food surplus which makes farmers go bankrupt) and produce won't be so expensive (thus less need for food stamps).
Or give employers the right to hire/or not to hire pot users.
If you think hiring pot smokers is good for business, by all means, go for it. But by that same token a company should be able to exclude users just the same.
