The banks should be limited to the existing government pay scales as long as they have the US government as a major partner.
You can find those scales at the www.opm.gov site.
The Military, the Postal Service, the Public Health Service, etc. are all paid in accordance with a primary standard ~ no civil servant or military officer may be paid MORE THAN a Congress critter.
I wouldn't limit a look-see to the top 10. Rather, if I were the regulator I'd simply note the requirement above and demand my partners adhere to it under penalty of law (fine, imprisonment, forfeiture, amputation, etc.).
They're bankers. They'd understand.
Ah, yes. But Congress can vote themselves a raise.
Limit CEO pay and pensions.
Oh, but limiting everyone’s is fairer ... except Congress.
I'd say that this is exactly backwards. Certainly more so when it comes to Military pay scales.
