Sorry it's both spending and cutting. the 2-5% proposed on income above >$250k a year really isn't the end of the world.
That said it needs to come with massive cuts because it's not enough money anyway.
Restoring 1980 tax rates for the top 50% of earners would make necessary cuts a helluva lot easier to manage. Raising taxes on the bottom 50% would be criminal, considering their radically reduced share of income achieved over the last 30 years and the fact that they're the people most likely affected by cuts, anyway.
I was a working adult in 1980, and I really didn't notice rich people having a tough time making ends meet, at all. They were rich, after all. Even then, they enjoyed the lowest tax rates of any of the first world rich.
