Democrats are trying to crush the middle class between the millstones of inflation and taxation.
Its what they do.
They hate the idea of middle class intergenerational wealth transfer.
They want everyone dependent and focused on the government (them) and that can’t happen if you don’t need them.
After all the tax cuts in the last 40 years (plus expanded child tax credits, etc), the middle class doesn’t really pay anything in taxes....certainly not federal taxes. About half the middle class doesn’t pay federal income taxes and the other half pays less than 10% of their income. Inflation is how they are effectively taxing the middle class without calling it a tax since any tax increase on the middle class is just not palatable.
