Sounds like a cool movie. Only in fiction are the Feds investigating and prosecuting anyone from Wall Street.

I think it better to say:

Money can buy you happiness.

It's very wrong to say that it never does but wrong to say that it does. Money buys lots of things: medical care, heroin to get high and enjoy it greatly, heroin to get-addicted-to, mutton, beef, trout, oral sex, a good education for a good job that makes you miserable…. My guess is that it greatly increases the chances to he happy, but apart from physical or mathematical truths, we absolutely must never, ever, make overarching unqualified statements.
