I don't think not getting caught is the objective for many of them.

They don't call prison "college" for nothing.

It's as if they actually plan to illegally earn and hide millions of dollars, go do a prison stint, and then get out and find the money stash.

Would you do 20 years in prison for 20 million dollars?

30 million? 100 million?

The problem is going to jail for too long for the more heinous crimes.

The problem is also in law enforcement allowing someone to commit a laundry list of offenses until they finally have not only enough proof, but also enough to put these guys away for a long time. Longer than these guys planned for.
