This debate reminds me about my story about the goals of the group in my progressive income taxes thread (which I may not continue working in for BS reasons...)
Simillar to what I would tell people at doors, I think we should remember that there is not just two options here.
We don't just need to have a flat income tax and cut welfare spending, or just increase taxes in a progressive way.
How about California cuts services and increases all of its taxes in a non-progressive way?
This radical plan for this thread only targets the poor when instead it should be a "shared sacrifice" I like to say to people.
