You can tell who the Boss is by looking at who gets paid the most

In real life bosses get paid more than stooges and flunkies.  Which is why we shouldn't be surprised that in American government employee's--local, state, and federal--make a lot more money than non-government workers.

Total compensation for government workers is 47% higher than it is for the people who pay the salaries of those government workers who work in the private sector.  That despite private sector workers working around 12% more hours on average than public sector workers.

Not only do government workers get better benefits--such as pensions that are fast disappearing from the private sector-- but they get paid more per hour.  On average government workers get 29% higher hourly wages than those in the private sector and 79% more per hour in benefits.

Further it's nearly impossible to be fired from a government job. Figure 1 shows the number of government employees vs year.  Note that the during the recent great recession government employment went up.

Figure 2 Unemployment rate by year

Figure 2 shows how unemployment spiked during the great recession.  Figure 3 shows the total number of full time employee's by year. Once again we see that while the average American had a good chance of losing their job in the great recession government workers had no reason to worry.

The bottom line is that the Democrats have created a new ruling class which is paid better and has better job security than the people over which they rule.

That class consistently thanks the Democrats by giving them lots of money. In the 2016 election cycle Federal workers gave 5 times more money to Democrats than to Republicans.
