Here are two articles that may appear to contradict each other, but don't when you consider Dems are economic illiterates.
1.Dems want huge tax cuts for the rich
They want to bring back the SALT tax deduction that let people right off on their federal income taxes their state taxes. The tax reform capped that at $10K. If the Dems bring SALT back, it will be one of the largest tax breaks in history. And it will benefit people in states with punitive levels of taxation.
2. If you are in the middle class, Biden wants to raise your taxes
Biden and the other Dems running want to eliminate Trump's tax cuts. That will slam the middle class like a tsunami. The average Joe got a $2000 tax relief from Trump. The Dems are furious at that.
