Beat me to it! EXACTLY! If the out of control spending is stopped there wouldn't be a need for 23% tax rate. I bet we would be looking at 10-12% tops. Cut all liberal arts funding (DoEd, NPR, Endowment of Arts, etc), cut all entitlement spending, eliminate Social Security (when implemented it was never meant to remain, it was TEMPORARY), eliminate ObamaCare, reduce/cut/eliminate the EPA, privatize NASA,...<quoted text>
That's just it! Cut the waste and it wouldn't take 23%. Entitlements are why taxes are as high as they are.
The reason for 91% in the 1950's was to pay for more than 10 years of war, supporting S.Vietnam, rebuilding Germany and S.Korea, and the depression. Also to support FDR entitlements he was so gracious with everyone else's money.
