Have a society where people like this can't get a foot-hold in the first place.
And organisations like Uber, Microsoft, etc. flagrantly broke the rules, got hugely rich off that, and all they got was ... a corporate fine. No personal consequences at all. Corporations aren't a force of nature, it's run by people and those people looked at the rules and said "fuck those rules, I'm going to break them for my personal enrichment". Bill Gates and that Uber asshole are still hugely rich.
We're letting the exploitive nihilists run the world, and all the lawmakers do is shrug.
- Don't shoe-horn "free market" into absolutely everything, recognizing that in some areas you need more regulation than in others.
- Reasonable anti-trust with reasonable enforcement.
- Personal responsibility instead of corporate responsibility (which is very rare today except in cases of outright fraught such as Enron, VW Diesel, etc.)
You can argue a bit about the details, but I don't think any of this is hugely controversial and has broad support across the political spectrum.
Remove limited liability to 'all asset paid by undue selling of share and dividend received, pierce the corporate veil _systematically_ in every fraud cases.
Bilzerian have a famous son who squandered the hundred of millions he stole and put in a trust before getting arrested, but I'm pretty sure defrauding people and putting the money in a trust, getting out of low-sec filled with other people like you after 5-10 year then living like a king shouldn't be possible.
Wealth tax. Increasing tax on wealth, capping at a 100% tax for wealth above $10M. Exact numbers negotiable, but that's where I'm starting the bid. When you've hit your wealth cap, it removes the motivation to drive up your bank account's high score (or at least makes it much more difficult) which is what drives most of this evil.
Unemployment. Render the entire concept of being an executive for a for-profit healthcare organization moot.
This can be accomplished with legislation. There's already plenty of established laws that prohibit non-profit organizations from doing (or not-doing) certain things[1], so it's not a stretch to have laws that prohibit for-profit organizations from doing other certain things.
...I'm only saying "legislation" because, by all reasons the free-market cannot support a for-profit health-insurance company: how can they exist at all when they're competing with non-profits for the same customers but who (like BCBS) don't have shareholder dividends to pay; so for UnitedHealthcare to somehow be both more-attractive to customers than BCBS (presumably by being cheaper) and still being able to pay dividends with whatever's left leads me to some very dark conclusions about how they operate internally. There's gotta be something the SEC can find and charge them with?
