A government of ideological purity is also a dead end. I agree with you that there is no excuse for tossing people out like trash because they cant keep up with the capitalist rat race. It's absolute bullshit, and proof positive the USA needs more socialism. The more robust the social safety net, the less that can happen.
You seem to need to misinterpret, and put words in my mouth to make your point, which makes the point questionable at best. A 'mix of isms' doesn't mean all isms should be treated equally, and the mix in the USA is horribly off base.
I want: stronger labor unions that encompass more industries, large increase in wages / the minimum wage. Four day workweek with no pay reduction. Massive reduction in runaway defense spending, and funds conditional on mandatory audits being passed. New improved trust busters equipped to break up modern style monopolies. Renewed focus on spending local and self/community reliance to reduce the power of mega corps, Policing reform with much more training and the requirement for police to carry liability insurance. Strong shift away from burning fossil fuels as an energy source. The list goes on and on, and I'm sure there are many points we agree on.
I do what I can as an individual, but of course I'm still working on it. What do you commit to? So far I'm not sure.
