I try never say never. I've been adamant against, first the Cloud concept, it's stupid, a ripoff and I avoid it every chance I get. Next, Windows 10, I swore I would NEVER ever go to Win10, I'd go Linux first. Well, I ran myself into a corner the other day, I saw an ad for Office 2021 at a good discount and as I'm still using Office 2003 I thought it worth the investment. Of course totally not thinking about whom I was dealing with I bought it and went to install it and it said MUST BE INSTALLED ON A WINDOWS 10 MACHINE. In that instant the "duh" was all over me! It was non-refundable of course, so I was stuck. But, I had a spare PC that arrived as Win10 and I hed converted it to back to Win8.1 and I thought ok, I'll just put 10 on there and install and whatever. So, I started into it and like all upgrades, nothing went well and after two days of fighting I won and got Win10 installed - the one thing I swore I'd NEVER EVER do?
The dream list you describe with term limits, no pensions etc takes us back to the founding days and the spirit of our governance - and that will NEVER happen. Maybe some limited terms and I can't imagine any of the perks of the job going away which compared to dolling out $30B here and $30B there is chicken feed. Why not doll out $30B to us folks living in inflation on Social Security? - but, I digress. The thing we all forget to factor into these hopes and wishes for elected people is that they are two things, humans with human nature and secondly they are snakes, that's why they became politicians. Once you accept those two things you understand why things are the way they are - at least until we the voters to change them.
