I've posted the links that show how the economy has been doing all along. You just don't like them because it doesn't fit with your narrative. The tax cuts do overwhelmingly benefit the wealthy. It will add to the deficit. The Treasury Department came out with an "analysis " not long ago and that relied on some improbable math. Even with that there are some cuts that will be triggered in programs like Medicare. And while the GOP is hyping the cuts I've seen nothing that indicates this will raise wages. That's going to be a problem no matter how well the stock market is doing.
