What’s wrong with national insurance? It’s unlikely to be MORE costly than the bizarre hybrid system we have now. What’s wrong with restoring former levels of funding to state schools, to make costs in line with 1980s or early 90s levels?
Even if taxes go up, you’d have 1990s level taxes with more return for tax money. I don’t see the big deal about Sanders. He’d be a moderate in another time. The main mistake he’s made is positioning himself as a “Socialist.”
