When a criminal turns state's witness and goes into the witness protection program, do they receive any benefits which may make them want to stay in the witness protection program?

1. Are they given a home and/or car?
2. Are they given money to start a business?
3. Are they given money to live on a weekly or monthly basis?
4. What kind of security protection are they given?
5. Do they get paid each time they testify in a court case? If not, do they receive some kind of reimbursement if their testimony makes them miss work?
