Illegal Immigration Prevention

The illegal immigration issue is a social as well as an enforcement problem. Everyone, it seems, has a reason for not enforcing existing laws, as well as not trying to make more laws and regulations, which might "solve" the problem.
As it stands now our legislators refuse to engage ina a serious debate and problem solving effort about the issue and refuse to raise sufficient funds and resources that would allow enforcing our existing laws.
Local police give illegal immigrants a "pass" because it is a "federal issue", the "system" gives employers the "wink and nod" to hire illegal aliens--it is no wonder that the U.S. is flooded with illegal aliens. The fact is, if we wanted to solve the issue we could. So far no one, other than the general public, wants a solution.
If I can come up with a plan in a few minutes thought, then our legislators ought to be able to come up with at least as good or better plan. In order to solve a problem a person should know what the problem is. In this case the basis of the problem is that illegal aliens are coming here (the U.S.) to find work, and because they are finding work, are coming here. Simple problem identity--no?
The solution--eliminate the jobs that are being provided to illegal aliens somehow. If an employer is approached by someone who speaks very little english I would think that would set off some bells. An employer is under no obligation to hire anyone, let alone an alien.
To get a job then it should be up to the applicant to "prove" his/her legal status beyond a reasonable doubt.
Besides the usual documentation, which can all be bogus, questions as to where they got their documentation, what schools they attended, towns and cities they lived in, addresses of where they lived in the past, knowledge of U.S. events etc. should be good clues as to whether someone is here legally or not. This sort of questioning, followed up with a call to Immigration and/or the IRS should eliminate most if not all illegal immigrants from being on someone's payroll. A stiff fine, say around $10,000 for each illegal alien hired should give those employers who cheat some pause. Especially when most of the responsibility and liability is put on the employers. Right now there are all sorts of dodges (legislative loopholes) that give employers an "out".
Giving out rewards to persons that turn in employers who hire illegal aliens should do much to help Immigration in finding those employers who cheat.
Everyone who has something to gain seems to have "pseudo" facts and statistics to further their argument. The average citizen can make up his own mind just from what he sees happening in his own neighborhoods. Whole communities are being taken over by aliens of every variety. Our politics has become multi-national--Cubans, Koreans, Jamaicans, Haitians, and more are effecting our local and national politics. Foreign nationalism is wagging the dog and making American politics multi-partisan and chaotic. Its about time to drop the slogans and get back to some semblance of reality. The U.S. is in trouble on many fronts. The sooner that fact is recognized the better off the country will be. The illegal immigration issue is just a symptom of decay. For a good idea of the decay process review The Fall of the Roman Empire.
