Since estimates are that 1/2 the folks in construction and building maintenance are illegal wage slaves of the capitalist stooges, I suspect that we would have to demolish a large fraction of the homes and offices constructed in the US in the last 10-15 years.
I would guess that a lot of the folks I see around Washington DC who do grounds maintenance are of questionable status. There is not a large hew and cry among the local unions about all of the leaf-blowing and grass-cutting jobs being filled at substandard wages. In fact, my guess is that the employers pay market wages for labor.
Whew, with your above passage, no wonder hillary has found a small constituency on FR.
BTW, when you all can show gestapo guards, pointing machine guns, at those "slaves" building houses, in America, then maybe you will be taken seriously, you won't though, for that doesn't happen in America, no matter your hyperbole.
