The SEC is, largely, a powerless bogeyman due to chronic underfunding and lack of staff. Another wonderful feature of corporate regulatory capture in the US.
Because we don't live in an autocracy, and government fines can (and are) successfully challenged in court. It takes an immensely greater effort, and immensely greater resources, to enforce a $5B fine vs a $5M fine.
Corporations have lobbied and purchased their way into these freedoms at the cost of our wallets and futures.
Don’t play thick. I too wish these assholes got prison time for this behavior.
In all seriousness, I'm a dyed-in-the-wool capitalist and I love the SEC.
