Corporate CEOs do go to jail, there are numerous famous examples just from recent history. Elizabeth Holmes, the Enron guys, Sam Bankman-Fried.

If your post was true then these rich people would have just lobbied to change the law in their favor and won.

But yeah mostly governments prefer to take their money for vague crimes that don't even apply to individuals at all, and then leave them to earn more. Much better for the coffers that way.
