Where is your proof?
Where I am I see illegal aliens doing 3 types of work:
- Computer programmer at the same rate paid citizens based on the same skill level, often 6 figure for the highly skilled or those in really short supply.
- Unskilled construction worker (eg carpet layer) in the $25/hr range.
- Unskilled cafeteria and cleaning crew in the $8-10/hr range.
In all 3 categories, the company spends large amounts of money and time trying to find people willing to work. The company clearly has a "prejudice" for non-immigrants. Especially the lower-middle management who control the actual hiring have a "prejudice" for non-immigrants. The simple fact is they cannot find people willing and competent to work.
There are many explanations for this. But the bottom line is there is a labor shortage. The law of supply and demand is at work. In a separate post. I'll propose a series of practical steps we could take to improve the situation. Each step could be implemented individually and improve the situation a little bit. But there is no one single step that is a miracle cure for all our problems. Some steps are more politically feasible than others.
Supply is a function of price. When illegals will do it for 10 bucks less, you have a huge economic incentive going on. Without illegals, the price for lower skilled labor would go up, and become more capital intensive. Income gaps would decline, along probably with the nominal growth rate.
