The economy is healthy in general, but let's look, once again, at some of the trumpeted numbers.
Unemployment is low now, however, this trajectory was established long before Trump's policies were implemented. The years of Trump have seen deceleration of the positive trend with a recent, very slight uptick in unemployment.
I haven't found the data you refer to regarding blue collar wages. If that is correct it is good news. There is a lot to accomplish. Here are some statistics on wage growth, corporate profit sharing and wage gaps. You can view and draw your own conclusions. I see some positive and some negative trends.
Consumer confidence is high relative to it's lows of the mid-2000's. However, this is another tale of trajectory. Other than a sharp negative spike in 2012, consumer confidence has been rising for 10+ years. Viewing the positive spikes of the last five years reveals a very flat trajectory. The spikes of the one previous year have a negative trajectory.
The stock market was in correction territory at the end of 2018. There has been a rebound in this first period of 2019, but we are still approximately 2500 away from the highs the stock market saw in 2018.
There is a patch of bad news in earnings presently, but there may be good news to come. Of significant concern are the predictions by respected economic bodies of a global slowdown.
There is also concern over the US strategy with China. The US trade deficit with China grew despite Trump adminstration trade policies.
At the end of the day whether or not the Trump adminstration will be viewed as a success or failure in the realm of economics remains to seen. In my opinion his views and strategies are simplistic, lack nuance and will ultimately have a negative impact on both the US and global economies. It's a little early, however, for victory laps from either side of the prediction spectrum.
