LEGAL immigrants are twice as likely to be entrepreneurs and are a wonderful contribution to their new country. They bring what the country needs and have the right skills and education to fit in and do well.

ILLEGAL immigrants are criminals who should be treated as such. By definition they do not bring the mix of skills, education and culture the country needs - thats why they didn't come in legally.

You write as if there is no difference between doing something legally and doing something illegally. It makes all the difference in the world.
