Would you support a mandatory retirement age of 75 for US House, US Senate & US Supreme Court Justices and if not why?

Lifetime appointments to the supreme court are obviously a mistake; the idea there is to make them secure in their jobs so they don't have to politik from the bench. It doesn't account for actually evil people digging in like parasites in the heart of our government. They should serve a single 10 year term, at which point no matter their age they must retire and then serve no further roles ever again. Like, you're not allowed to go be a senator, or a congressman, or a governor, or a Walmart greeter. You can volunteer to speak to law students, you can retire, or you can die. Minimum punishment for a sitting or former supreme court justice for any crime: jay walking, copyright infringement, speeding, embezzling, mass murder: instant death. The guilty/not guilty verdict is read to your firing squad. The members of our highest court should be nothing less than absolute exemplars of citizenship.

The house and senate should have maximum terms of not ten years each; the senate currently has 6 year terms, that would have to be shortened, possibly to four. Wouldn't hurt my feelings if we eliminated those mid-election years so we could have some time away from being screamed at by our so-called government. You want a full career in politics? You start at the local or state level, then you run for federal office.

I would make prior office a requirement for President. As far as I'm concerned, you have no business serving as president if you have not already been a senator, congressman, governor, state senator or general assemblyman. I do not believe town council or city mayor should count here because of the low barrier to entry for buying 10 acres of rural land and incorporating it as a town with one resident and electing yourself mayor.
