Yet legislators in Kansas, not trusting the poor to use their (emphasis added) money wisely,...
It isn't "their" money if they are on welfare. It belongs to the taxpayers who were forced to pay it to their government. And the government legislators elected by those taxpayers have the right to decide how those funds are to be used by those who receive them. With things come strings. If you don't like it, get a job and earn your keep. No one will bother you then about how you spend your money. (Except they'll force you to pay taxes.)
If the Left had their way, we’d all be getting monthly stipends like they get in Cuba.
