"Efficient government spending" is a funny concept. Would love to see that one come to fruition.
Part of the reason why wages haven't really increased since the 2009 recession is because firms are sitting on cash for a number of reasons. Real wages have most certainly
not increased over time, a trend that probably dates back 20 or 30 years, or potentially more. Real wages are wages adjusted for inflation, which is a measure of purchasing power. It's pretty obvious that the powers that be want to hide inflation in any way possible, because the inflation is what allows the government to keep running huge deficits and places upward pressure on stocks and other assets so that Wall Street can keep the derivatives game running. But this obviously hinders the average Joe from being able to save and create wealth for themselves, especially if they have to spend 10% more on paper towels from Wal-Mart year over year.
You say a tax cut for the rich is a "wealth grab." That makes it seem like they stole the money from someone else in the first place. Maybe you could argue that for some, but that wouldn't have been possible without the Fed's artificially low interest rates, IMO.
Edit: Here's an article that explains this premise.
