Not for ten times that money. Sure some people can think time and work pay and do the numbers to think "2.5 million dollars a year and all I have to do is go to prison?" There's a whole lot more than that. $10 million doesn't go as far as it used to, and a felony rap is no joke.
Losing the ability to travel, especially internationally
Losing my license to practice law, felons are automatically disbarred in most states so that'd be three years of my life wasted
Losing the ability to have gainful employ in most jobs, felons are not a protected class
Losing time with family and friends
Losing family altogether, many family members would not speak to you again
Losing kids/marriages, four years is a long time and you probably aren't getting custody after
Losing most benefits, think of paying into social security for years and not being able to collect later in life, $10 million isn't that much in 2020 and some of us have a lot of years left
Losing the right to vote in many states
Losing the ability to own a firearm
How would you explain this on your taxes? Paying someone to commit a crime (and collect from said crime) is extremely unlawful so the money you have would be illegal, and using it in any significant way (without special help, which costs a lot of money) would get you put back in. Assuming this four-year stint and the crime to put you there is a one-off, the ill-gotten gains are a risk for years.
You would come out a different person, four years locked up. Doesn't matter how tough you are. You'd be forever changed, and not the same person as you went in.
Finally, losing your freedom for four years
No thanks.
