Many tell us what to think. I ask my readers to be skeptical. Question me and others. 
Twenty years ago, Congress presumed how fast the economy would grow in the future, and how many foreign workers it might need. It passed immigration laws with quotas specifying the number of immigrants allowed in to the country every year. However, even Congress cannot predict the future. Economy grew faster than expected, absorbing 12 million more people than bureaucrats anticipated. Instead of eliminating the hurdle of these ridiculous immigration laws, now lawmakers want to build a wall to stop new workers from coming. If reality disproves what politicians envision, it is bad for reality.
