Much of the theory I'd been supplied (mainstream economics, an unbeknownst to me at the time hardline Libertarian professor in my intro course: https://news.ycombinator.com/item?id=22133958), was false.
Undoing the damage of false priors and models, especially under ongoing objection and denial based on those, is difficult and expensive in time, effort, and willpower.
At least now. Less so in my younger years.
