The FR pro-illegal Quislings shrink from any questions about the public cost of illegals as does Count Dracula from sunlight.
BTTT!
I know that you have a "source" of facts to support your position but you understand that those who create legislation and policy have a different set of facts. These people in govt have to use facts that come from sources that the court would recognize as credible. Your source is not credible and were Congress to create legislation based your facts, their legislation would be successfully challenged in court.
There have been numerous studies on the economic impact of immigrants(legal and illegal) done by recognized credible governmental and non-governmental groups. The study done by the Dallas Federal Reserve Bank is considered to be the gold standard.
And yes, there are differences in your facts and these other sources of facts. But these differences in facts is not the the most important difference.
What is most important is how the economic impact is measured.
Your facts uses what is called the snap shot method. It measures the economic impact at a one and only particular point in time. Economists measure the economic impact thru time. Long periods of time. Even into subsequent generations.
An extreme example of this is the illegal known as the "Tomato King". Way back when he and his wife snuck in and he was picking tomatoes it is no doubt that their impact was negative. But thru time he became a labor contrator and further thru time he invented the tomato picking machine and became rich. There is no doubt that his economic impact, thru time, was highly positive.
Another extreme example is Mr Gonzales and his wife who no doubt had a negative impact in the beginning but thru time that impact lessened and eventually turned positive. If you consider their subsequent generation, who became US Attorney General, you would have to say that that their impact, thru time, was highly positive.
These, of course, are extreme examples but the mundane examples work under the same principle. Juan Perez begins sweeping the floor in a factory but gets promoted to spot welder, leadman and eventually foreman. Thru time his impact shifts from negative to positive. His children learn the language, the body of knowledge, and pop culture. They assimilate and contribute more than their father.
If I were given the job of measuring what you contributed to society and the economy, surely you would want me to measure your whole life's contribution , not just what you accomplished up to age 24.
