Once the prevailaing wage demand is issued, and strikes ensue, the demand for work will diminish significantly due to cost. Then the millions of people here legally but unemployed will demand medicare, medicaid, unemployment insurance, etc. Atually, the leftist pols will demand it for them. It is very unlikely that the left will allow deportation of green card holders (or legalized immigrants) due to unemployment. They seek to raise taxes and encourage hand outs as an investment on votes once the illegal becomes a citizen and can vote.
No then all of those willing citizens will line up to work for the prevailing wage. Isn't that what all of the close the border folks keep saying? We will see millions of white folks on roofs, busing tables, mowing lawns cleaning toilets. All of those jobs both blacks and whites are just itching to get their hands on.
