I am using U.S. Census Bureau data, which does not collect data on the legal status of foreign-born individuals, so it is impossible to distinguish between immigrants and illegal immigrants in the census data alone when discussing labor participation and education. Crime is a different beast and does distinguish. That is aggregated by the FBI, so those numbers are accurate.

I based these myths on what is said on the right without proof.

Education vs. intelligence - I am not mixing the two up. Education measurably affects economies. Intelligence is a character trait that cannot be measured. Of course, some people claim it can be measured by IQ tests - that test invented by eugenicist racists to cull the masses.
