I live in California, in the San Francisco "Bay Area". I have read numbers of estimates up to 20 million in the U.S. - having passed through many States, I believe this is probably more on the mark. Living in California, Southern California and the S.F. greater Bay Area have huge numbers, of these they are not the typical "picking grapes" crowd at all, and many of these are criminal, political (leftist), young "Mex-Rap" types, they do NOT fit the stereotype of the old media at all. Some of these hang out in front of home improvement stores, or gas stations, in large numbers, and businesses in violation of US laws illegally use this labor to cheat the taxpayers and undercut the going wages to the demise of many honest hard working Americans. These businesses are involved in political corruption in alignment with corrupt developers (who will now use corrupt domain laws to declare areas “blight”) to build houses and condos which actually do not met regulations because those who are doing the building (illegals) have less than a sixth grade education and are delivering less-than-standard edifices and construction which is not inspected simply because the politicians do not want the public to know just how much illegal labor is used by such developers who donate to these politicians campaigns. Democratic Party operatives use the same illegals in massive voter fraud, I have personally seen the vans picking them up and taking them to voting places. Outside the Bay Area and major cities of L.A. and San Diego, you do have the agricultural workers, the big agra-business is also involved in massive irregularities through such illegal use of roundabout labor, which is now risking our health in some cases. There are also known cases of the ownership of such big agra using the (illegal) women as their personal sex slaves and such, the owners have personal relationships with influential illegals who run the human cargo about, these “cargoes” which are an “aristocracy” of select illegals own very, very expensive, custom, Chevrolet Silverado and Ford F150 and F250 trucks, and some of them are now driving Hummers and are becoming increasingly involved in the marijuana trade. Young “hot shot” Americans in the valley work with these illegal “cargoes”, praising their trucks and encouraging the corruption, they don’t give a damn about laws and it is sad to see, increasingly, better off American farmers in the valley becoming corrupt, in almost every case these are younger ones (in the mid-thirties) who were having a bad go of it until they decided to “go along to get along” and are now deep into the entire illegal alien “cargo”.
