Here's the problem with todays society...employers are resorting to cutting costs wherever they can which includes wages. If they can get away paying illegal immigrants low wages in cash which are more than they can make in their country, they are going to do it. AND by doing so are taking away from Americans looking for work. Anyone found to be working illegally should be deported back to their coutry on a get home free pass provided by the employer. Any employer caught employing someone who is not a registered American citizen should also pay large fines which would go to an account that will be dispursed to citizens of that state.
There are ways to harness the methane to large generators which in turn provide an unlimited amount of power. By doing so creates a demand for equipment which creates jobs making and maintaining these machines as well as maintaining the operating facility.
