They should be taxed more. They dont pay any income taxes as it is.
If Republicans were smart, they would actually get behind those who don`t pay any income tax instead of singling them out for not doing so. Start with them and build from there and you may actually have a foothold in getting something like a National Sales Tax (which I support 100 percent) or a Flat Tax (Which is also a good direction to go in).
But no, instead, they are thrown under the bus when they should be the ones being supported. They are cast aside by them because they have no intention of EVER changing the tax code other than by a few percentage points here and there.
Republicans, get your act together.
