Am I reading your comment correctly? GP says that, over 30 months, the average American makes $125k. Given a $68k per year average that you provide, that's $170k after 30 months, which is even more than GP estimated. Even if the average were $40k/year, that's still $100k after 30 months.

If 700k - p_caught * (value of 30 months of your life + 700k + reputation + fines) is greater than 0, a rational and amoral person should execute the trade.
