What Would Be Your Plan to Correct The USA Economy?

Why does not the USA choose 10,000,000 people that operate businesses in other countries to become USA citizens and charge them 50% tax for 10 years (that would bring in an extra $100 billion a year) with no use of government assistance programs, in order to take care of our citizens? Why are illegal aliens able to use Medicaid, Medicare, or Welfare (this would save us $100 billion a year, so now we are up $200 billion)? These new 10,000,000 citizens in holding would be required to buy a home over the next year divided by 3.3 (the average size family coming in) so roughly 3 mil homes would be bought up, that would go a long way, and at least that market could begin to stabilize. The federal government could place a moratorium on builders. Take charge of lending & getting rid of lenders and investors all together, and allow citizens to borrow at the same rates banks borrow at, "such as under 3% interest only per year"and really act in the peoples best interest. WOW! Would not it be great if our gov would really be the peoples government? Drill our own oil, as we seek other energy sources, such as nuclear and other clean energy.
