There is only room in our political system for two viable political parties. You can argue all the “what ifs” all you want, we don’t have rank choice voting, aren’t likely to get it anytime soon, and desperately need a real people’s party. So, we take an existing progressive party (the Greens), destroy what’s left of the corrupt Democrats, and replace them. Far from simple. The Democratic establishment will fight tooth and nail to defeat us, already have and are. They have the big money that isn’t Republican, after all.
As to the relative stupidity of globalization and self-driving cars, neither is an answer for what ails us. Cars and more “happy motoring” will not continue, and we can’t play on a level field with countries that force their citizens to work for pennies. Localization, re-urbanization, and transit are the long-term solutions.
