Liberals and Progressives can't see that the economy is being suppressed by over taxation. The Laffer curve shows that there will be more revenue for schools and government by the use of effective tax cuts if there is overtaxation.
When business thrive and home values start increasing so do property taxes revenues (which supports most schools in this country) start increasing.
Simply stated, Progressives and Liberals are stuck with a static model of taxes in their brains. They believe that you will ALWAYS get more revenue from More taxes all the way up to a 100% tax rate.
It does not dawn on them that revenues can go DOWN because a suppressed economy decreases tax revenues. So when they increase taxes and the revenues go down, they have no choice but to increase taxes again.
That is why you should never trust a politician who even suggests increasing taxes.
I once said to my liberal SIL and my liberal brother that taxes, rates and fees can and will change human behavior. You would have thought a fuse popped in their heads.
