I would easily go to jail for 8 years for $50+ million. 25 years would not be worth it to me for any amount.
I am from El Paso, which is on the border with Mexico and grew up with many kids whose parents were smugglers and cartel affiliated.
I know several parents who went to jail for ~10 years while were were in elementary school, the kids never wanted for anything, and then when the parents got out and started capital intensive business.
One parent did 12 years and got out to start a a series of high end mexican restaurants, one started a steakhouse, one bought a small hotel, one started a commercial construction company.
It's all part of the game, just how startup founders grind for years for the money.
Honestly? I sincerely doubt you, or anyone would actually, really, for realsies, go to prison for eight years for $50M. Anyone would beg to be released after a few weeks.
That is a complete middle class mindset. Jail is cool in the hood. I've done a few months for stupid stuff when I was young and it's not that bad.
People risk 10 years for robbing bands for a couple thousand. A guaranteed $10 million would have lines around the block for volunteers in the neighborhood I grew up in.
