Disclaimer 2: A lot of what I am going to say here seems impossible, from a political standpoint. It probably is impossible, without major cultural and social changes. It would be hard... but not as hard as going without food and water.
Disclaimer 3: This is really long. I should be working on grad school work, so I should not have just typed this all out.
