Energy independence
Environment
Healthcare/hospital cost control - Title II
Deregulation - airline, trucking, rail, oil - mostly adopted
Mental health care -
Obviously each could splinter into a long debate - pick one and research it on your own if you are actually interested.
I'll start by giving you one:
I can definitely see some pain/gain from those, but even what you quoted noted some paradoxical actions in what you mentioned. particularly the first two. the rest seems like some gains, but not in the mindset of the short term pain for long term gains.
he helped protect the environment, but his push on energy independence relied on increasing domestic production, including the creation of synthetic fuels made with coal. so even in this case Carter wasn't fully dedicated to long term strategies he founded.
title 2 reads like robbing Peter to pay Paul situation. Using increased Medicaid funds they were able to reduce the cost of drugs people on Medicaid paid. at the least, its a bit circular, and I don't see how it would have lead to any long term gains.
On MHSA, mental health, I also struggle to see the long term gain. seems like its the current strategy, just years earlier. lots of medication, it did de-federalize the system which could have lead to some longer terms gains than the previous one-size fits all, but I am not sure where the "pain" was there. I think there is a lot of good here, just not seeing the current pain for future gains we were discussing.
the deregulation would probably take a long time to break apart. but at the 10,000ft wikipedia level I am again not really seeing the "pain" aspect. it definitely cut red tape, so there were long term gains to be had by Reagan, but no short term loss/suffering/pain.
