The government may not have standing to sue on the worker's behalf.
The agency that prosecutes tax fraud may be larger and better funded than the agency that protects workers.
One tax evasion charge may combine the cases of thousands of affected workers into one case, where the individual cases are too small and time consuming to pursue.

2) Unpaid overtime is not really unpaid unless your employment agreement explicitly states that you are not supposed to work more than 40 hours. If you get paid $100k to work 50 hours, then you are getting paid $100k to work 50 hours, not $100k to work the first 40 and $0 to work the next 10. Your comp is payment all the hours you work, not just the first 40.
Of course there are exceptions, such as programmers.
