Everytime I look at small problems or big global problems, if you follow the money trail, it all leads to some billionaire who is either working towards increasing their wealth or protecting their wealth from decreasing.
Everything from politics, climate change, workers rights, democratic government, technology, land rights, human rights can all be rendered down to people fighting another group of people who defend the rights of a billionaire to keep their wealth or to expand their control.
If humanity got rid of or outlawed the notion of any one individual owning far too much money than they could ever possibly spend in a lifetime, we could free up so much wealth and energy to do other things like save ourselves from climate change.
Wealth disparity and concentration of power into a corrupt ruling class of plutocrats gets pretty toxic to human rights and democracy pretty quickly.
Listen to some behind the bastards episodes, look into people like the koch brothers, or Amazon’s union busting, or any of the large political scandals in the past 100 years (eg. Like the business plot) - and you’ll usually hear of some wealthy ahole involved funding some shitty attack on where ever.
