What happens if you are caught entering the us illegally?

It's a sad but fact of life that the tax payers in the uk not only get turned over by the tax man but by the so called unemployed of this country we as the working class pay our tax and NI every month to help those that can't find work for what ever reason just left school are at that point in there life where the classes by employers to be at the top end of the employment age group and there them that just can't be bothered and for the latter of the three they feel that it fine to take the kind tax payers money and claim benefits then go and find them selfs a cash in hand job because they say the government don't give them enough to live on so I thought that I would look in to what happens to them when they get caught out and it appears to be a sad fact that really nothing happens to them

The first time they have the giro stopped for for weeks the second time they have a sanction put on them what is wrong with this country if u rape some one you don't expect to get away with it so why when you rape the tax payer fort there money HARD EARNED MONEY do u get away with it
