I understand what you are trying to say but think about this. If you took all the people on welfare, all the non violent offenders and put them to work doing the work that the illegals are doing, where would we be then. We would have a society that understands the value of a dollar and maybe would think twice about having that third child on welfare, or using their hard earned money for dope, or not paying their child support. Instead we give them money, food and health insurance and when they are in jail we feed, house and give them tv rights. So, put everyone to work, and if we have to give them some subsidies such as food stamps, housing or medical..so what, we are not giving it to illegals? we still are generating income from their taxes. So, in answer to your question who will do the work? there are plenty of options it just takes a government who takes a stand against welfare, crime and illegals to make the necessary change.
