Sort of like LBJ's war on poverty? What's the figures regarding cost vs effectiveness on that?
I really have to laugh at those on the left that use the fiscal argument when something they don't like is proposed. The same people that judge themselves based on intentions instead of actual results will apply totally unreasonable criteria to anything they don't like.
Funds have already been allocated. The money is there at least in theory. Building it is easy, humans have been building walls forever. It absolutely will not be 100% effective. Little if anything is. The wall along with enforcement of existing laws,, human and high-tech monitoring will result in enormous reductions in both illegal immigration and the movement of drugs into the nation. (I can't help but think that the drug aspect is the one most upsetting to many.)
The left wants everything. They want it and they want it now. Free healthcare, high speed rail, free education, magic sources of clean energy, the list goes on and on and on. And they want it for all the people of the world. If you can sneak in here, you should be entitled to it too. What, you're seeking asylum? Well, here's your subsidized this, this, and this and your subsidized that. What they can't wrap their heads around is that we don't have the money to do the things they want because they can't prioritize. They want it all.
The times they are a-changin'. One constant in life is change.
