Optimism. And I know it won't sustain growth, like love don't pay the rent. But people who run businesses(and that includes the evil corporations)understand that a low tax rate and an increased profit margin(I know, I know, I said "profit", which makes me a racist)is good for the economy. But if you want to RAISE taxes, RAISE the minimum wage, INCREASE regulation, and it results in a stagnant economy at best, what do you expect business to do? Why would they hire anybody, much less increase wages? The left has convinced much of it's voter base that the only solution to "income inequality" and all that other made up gibberish, is to raise taxes and redistribute the booty to those the gobblement thinks deserves it. In fact, some very smart people are now promoting the idea of a "national salary", which as I understand it, is getting a check from the gobblement simply for being an American. WTF? Is this the sign of a healthy economy?
