The biggest crimes are rarely prosecuted. White collar crimes that crash entire companies and cost people millions, or even billions, of dollars, probably causing more than one suicide and ruined livelihoods are simply 'whoopsies' nowadays. Even in the old days when they were prosecuted the penalties were light. Nick Leeson in the 90s was a rogue trader who singlehandedly destroyed Barings Bank in the UK. Barings was the biggest merchant bank in the UK, and like many British institutions it was very old and very established... they brokered the deal between Thomas Jefferson and Napoleon over the Louisiana Purchase, that's how old and influential they were.

But Nick? He fucked up an entire bank of massive proportions in a few years. All while trading in the casino that is the Stock Market in Southeast Asia. His penalty? A few short years in a fancy prison, and he didn't even serve his full sentence. His post-prison life was prosperous. He has (or is) managing sports teams, written well-received books, and overall is doing quite well for himself. Compare this to some teenagers who did some stupid vandalism out of youthful stupidity and ended up with records that haunt them for decades.
