Filibuster is for legislation that needs 60 Senate votes, tax changes only need 50.
There are also quite a few Democrats in swing districts who I bet will vote for tax cuts. They are basically only in office instead of their Republican opponents because their opponent opposed women’s rights.
That's not quite right. Nothing (or almost nothing?) needs 60 Senate votes to pass. The difference is that they've agreed not to filibuster tax laws, and you need 60 votes to break a filibuster.
So you're right on the practical effect, but the details are slightly off.
