Trump is NOT just against illegal immigration, but also excessive LEGAL immigration:
“Every year, we voluntarily admit another 2 million new immigrants, guest workers, refugees, and dependents, growing our existing all-time historic record population of 42 million immigrants. We need to control the admission of new low-earning workers [...] Raising the prevailing wage paid to H-1Bs will force companies to give these coveted entry-level jobs to the existing domestic pool of unemployed native and immigrant workers in the U.S., instead of flying in cheaper workers from overseas. [...] Before any new green cards are issued to foreign workers abroad, there will be a pause where employers will have to hire from the domestic pool of unemployed immigrant and native workers. This will help reverse women’s plummeting workplace participation rate, grow wages, and allow record immigration levels to subside to more moderate historical averages.” - https://www.donaldjtrump.com/positions/immigration-reform
AND RIGHTLY SO:
“Legal immigration threatens our society” - http://www.freerepublic.com/focus/f-news/3322390/posts
If you don’t address the problem one step at a time, you’ll never solve anything.
Making the distinction between LEGAL and Illegal immigration also has the advantage of fending off the racism charges.
