That's that stupid law they wrote to reduce the number of starting jobs, reduce the number of businesses working in the U.S., and curry favor with the liberals.
Retrain the to do what? There are only a limited number of service related jobs that can be created
There are active sectors here in the U.S., with new ones being created on a regular basis as people think up new ideas.
You don't need a wide open field, you just need to be better than others.
No guarantees in a free system, but if you will work, you can work.
Shalom.
