The link you provided is simply the progressives wanting to return to the 1970s tax rates. Ms. Ocasio-Cortez (economics BA degree) assumes there will be a "windfall" that can be spent on gov't green programs. I seem to recall Reagan's cut in tax rates (passed by a Dem house) increased collected revenue substantially, the econ BA doesn't seem to understand the risk in returning to the bad old days.
Dem Senate and Assembly members aren't dumb; rather than vote their hearts, they put the lower threshold for taxation on the ballot to see if the people of CA will approve it. And they will, if recent history is a guide (see you at the polls, Cheryl, we'll cancel each other, ha!)
