To avoid the trap of post hoc ergo propter hoc one must eliminate other contributing factors. First, it is not clear that the government's numbers on unemployment are honest. The evidence to the contrary is abundant. The government has changed the way it counts even if it renders an honest count.
Second, immigration has flooded the labor market and some qualified observers have argued that all growth (repeat, "all") since the great recession has gone to immigrants, many of them illegal. One might well ask why this AFL-CIO has not taken the lead in opposing a policy which deprives its members of jobs?
The answer is as one poster on this thread is already pointed out, it is all about dues and the triangle trade of a kind of modern slavery: workers are required to pay dues as though they were in involuntary servitude, a percentage of those dues go into the pockets of union leaders, and a percentage goes into the coffers of the Democrat Party which passes laws to protect union leaders, often at the expense of rank-and-file workers and dues payers, as we have noted, concerning Democrats who support illegal immigration.
It is our liberty, Mr. Becker, which is the culprit but it is your union, your henchmen, your political party and your president.
bttt!
