I should preface this. Economically I'm a socialist. So a 7.3% figure is still really bad to me and entirely unacceptable. By definition a portion of the population must be unemployed (and suffering) in order for there to be a labour market for capitalists to exploit. I understand that true full employment isn't possible without fallible economic planning. However, 7.3% is far too high in a country without good social safety nets like in the United States.
With that out of the way, you're right I didn't give good context. Most of the jobs created since the 2008 Great Financial Crisis have been in low paying industries.
Which means that most people who lost their jobs during the recession who have returned to the labour force now have a significantly lower quality of life then they previously did. Meaning that the unemployment rate the media is raving about is missing context (possibly deliberately) and the true state of the economy when compared to before the recession is actually sickly. We haven't recovered nearly as much as folks think we have. Combine that with the inability of central banks to artificially subsidize the market through a capitalist form of central planning (quantitative easing and the precluding fraudulent classification of subprime debt as investment grade by the treasury department to take an example) and we're ripe for a bad recession. The same mistakes that the U.S.S.R made are being repeated by central banks and governments right now. Not in the same exact flavour, but the spirit is there. The statistics are spun by an inaccurate ideological lens and portrayed in such a way that things don't seem as bad as they are. It also wouldn't surprise me if some of the statistics are outright lies and or exaggerated truths. Historically the U.S.S.R did do that, as have other slowly waning empires, we are no exception as conspiratorial as that may sound. And America is an empire, a commercial empire, but an empire nevertheless. We have over 800 overseas military bases and are the most powerful empire in world history.
Another anecdote is that when looking at the historical unemployment chart (not U-6) it seems that low unemployment on the tale end of a contraction of the labour market is a good indicator of an approaching recession, not an indicator of stability or a healthy economy. Capitalism lives in a cycle of crisis, and looking at the historical unemployment chart shows we are in the tale end of one of the largest labour market contractions in U.S history.
As for protests and riots. In my city alone, Pittsburgh, there have been two major events of unrest over the past year. The first being the murder of Antwon Rose by a so called "officer of the law." This resulted in thousands taking to the streets and protesters blocking the interstate tunnels entering my city. Some of the protests were very energetic and frankly angry. Some of them were classified by the state as "riots" despite the protesters being non-violent in nature. I myself helped run a small water brigade to make sure folks didn't get dehydrated.
The second major event was the synagogue shooting at Tree of Life which saw the Mayor of my city refusing to invite, welcome or greet the President of the United States as he was shouted out of town by a crowd of protesters.
The mayor of Pittsburgh, Bill Peduto, who just a day before had urged the president not to visit while the mourners buried the dead, neither met with Mr. Trump nor joined the protests. The top four Republican and Democratic congressional leaders who were invited to join him all declined.
This is the definition of a stressed and divided country. I've been seeing that boiling point simmer in my city for a while now. The same pattern is visible across the country from Ferguson to Baltimore to Occupy to G20 to the Women's Marches to Charlottesville.
