The problem of immigration

no matter you are from Argentina, Italy or the united states, the immigration problem is now the cancer of every minimally developed country, economically as well as socially, I say I am tired of the rapes, murders, thefts, carried out by these dirty vermin.
it is undeniable that people like Mexicans, North Africans, Arabs and all these riffraff have a propensity for crime, many leftists argue that it is the fault of the citizens, who are considered racist and reluctant and the state, which in their opinion proposes too few economic subsidies, the question is: why don't they go to work like you and me instead of being gangstars and bullshit? No No No
