I'm sorry but I don't think the 80s are really something that can be explained to someone that didn't live through them, which I assume you didn't, otherwise you wouldn't be asking for clarification on Reaganomics.
I loved the 80s so much more than the 70s, so I'm not sure where you are coming from.
EDIT: I did remove an insult from an earlier draft of an earlier comment that you were probably a kid (as most people here are) that didn't remember the 80s. Since you are apparently not, my question still stands. (I don't have a pin-up of Margaret Thatcher any more, though...)
Not sure what's expected here. I mean, this is hardly the format for 20 page dissertations on lived history. I'm guessing these downvotes are coming from folks that are missing context because they're in their 20's and don't actually know anything about Reaganomics, what was proposed vs what the actual observed outcomes were, etc.
Can you explain your claim 'objectively true'? There are too many non-concrete nouns running around for me to be able to keep track of...
