As to the drug testing...surely you can see a government hand out =! legal tax deductions? To allow this not to be challenged as a false equivalency is to continue to allow folks to make the case that everything we earn basically belongs to the government and we're allowed, no doubt due to governmental benevolence, to keep some of what we earn.
I suppose it depends on how you view some of those government transfer programs.
You could make an argument that the hand outs are simply a part of the tax system...they are tax credits so large that they turn your tax bill into a net positive amount. If that's the case, then why are you drug testing for one type of tax transfer payment, and not drug testing for another?
I don't think either should be drug tested, and I recognize that she is doing it as a farce, but the only reason it sounds funny is because of the framing.
