Your experience was much different than mine. I was in college when Carter was President, and he stopped food stamp benefits for poor college kids. I often went hungry. I'd voted for him, voted against his reelection.
Under Reagan I worked for Disney. Reagan slashed the capital gains tax, which unleashed an orgy of hostile corporate takeovers, one of which was unleashed on my employer, who took a big financial hit from its defense and cut everyone's hours. I had trouble paying my bills for a while. There were hundreds, perhaps thousands, of these hostile takeovers and takeover attempts. Of course, a recession followed this but none of the pundits connected the dots and they treated Reagan like a demigod.
We moved back to Illinois when Leila was born, and it took well over a year to find a job. Thanks for the recession, Ronnie.
I got a job finally, in 1987, but half the people I knew were looking for work until the nineties. That was Reagan's fault, but Bush did nothing to alleviate the situation.
There was something about Clinton I just didn't like; he came across as a sleaze and I think I voted Libertarian that election, I don't really remember, but it wasn't a vote for Clinton.
I was wrong about him; he put 100,000 new cops on the street, and my crime-ridden neighborhood got a neighborhood cop and crime plummeted. He signed PWORA which ended generational welfare. I voted for his reelection.
As to Bush II, can you name a single positive thing he accomplished? I can't.
As to Obama, my opinion of his mediocre President went up a little when he started opening Cuba; it's long overdue. We've had relations with China and Russia for years, it should have happened when the Berlin Wall came down and the USSR split up.
