It's not surprising that liberals suffer from this delusion - it permeates their thinking on every topic. No matter whether we're talking about minimum wage, college educations, or immigration, liberals cannot understand that the very source of a thing's value derives from its unequal distribution. In other words, the more scarce a thing is in relation to the demand for it, the more it's worth. A college education used to command a large salary premium because there weren't as many college graduates as there was demand for them. Now there is a glut of college graduates and they're not worth as much. If 100% of people receive a college education, it will have no economic value whatsoever. The same holds true for the supply of low-skilled labor. It's astoundingly stupid of liberals to support open borders and bemoan the plight of poor people at the same time. They're literally driving the value of jobs into the ground with their ideology and then complaining about it as if someone else is responsible. If they really wanted jobs to pay more they would know closing the immigration spigot would have that result immediately.
