Went to school for environmental engineering almost twenty years ago and graduated with one of the first accredited degrees in the field.
For the last twenty years I've traveled the country helping clean up the environment or prevent land from being further contaminated. Yeah the system is fucked up, lawyers and politicians and society don't value the environment over a quick buck. But I've done some good as opposed to wave a sign around at a protest.
Built up enough experience that I'm now part of a specialized team with the EPA that goes to all states and territories to help with case development on complicated or high profile sites that states and regions don't have the resources to handle.
Doing exactly what I wanted to do for my career, and directly because I got a good education that opened the doors to do it. I make a decent salary and have a skillset that makes employment easy and secure.
Bring back tax rates of 90% again for the obscenely rich - it was that way up until the late 1900s. Back when the US actually funded things that benefit most people not just tax breaks for already rich people.
