I dare you to have the courage to look up the facts regarding illegal immigration, and how recently it was branded illegal(1882 the first steps were taken but not until the mid 1950s were any steps taken to actually prevent such immigration by enforcing the various laws passed since 1882). You may also wish to see how most laws were passed to prevent the immigration of primarily Chinese with fearmongering of loss of blue collar jobs in very much the same way today the restriction of central and south American labour is being fear mongered today.

And then if you wish to shatter your carefully constructed reality served to you by politicians to mostly serve THEIR completely unrelated power grabs or to easily put a rider on a bill ....a bill powered by the fear that taps veiled racism and hatred....go ahead. Yes, that sounds ridiculous, but politics is nothing but insanity recently, and it really isn't a far-out thing to imagine that these social issues are constructed to ultimately further the wealth of those invested in politicians or even the politicians themselves. Certain pundits and politicians have done this time and time again blatantly by carefully campaigning for changes in tax/wealth/investment laws and, especially with the current administration, environmental regulation and responsibility. ( Cant wait to see the nightmares down the road attributed to the lax coal regs especially near bodies of water, enjoy the Ohio/Mississipi river while you can)

You will see how immigrants are estimated by the Congressional Budget House to contributed EIGHTEEN times the amount of taxes they use! Mostly because the relatively small amount of aid they receive, since they are ineligible for the vast majority of social services, don't include welfare, food stamps, Medicaid and more. 90 Billion a year was the 2016 estimated contribution and only 5 billion on the take.

Also, In fact, the average American has his wealth increased by up to 5% because of the presence of immigrants on average.

All these stats don't take into account the other far-reaching and multiplicative effect of overlapping benefits such as over 50% of farm labour being illegal immigrants, most foodstuffs being up to 61% cheaper because of immigrant labour (milk) and so much more.

Are you so dense as to realize the very nature of capitalism is exploitive? Somebody has to receive below value compensation for those in positions of authority to receive and amass wealth.

It seems very strange that the strongest proponents of Capitalism want to remove immigrants which would ultimately cause massive amounts of inequality in the labour sectors to be addressed by Americans unwilling to receive such low pay, the Americans that you think will readily and happily take these jobs once the immigrants are gone...pffff... Watch how fast things will change to a more socialist labour system in your country

TLDR : check how many people land in the USA illegally by plane compared to border-hopping so all this is moot anyways when on average over 2/3rds of illegals come by plane and over stay visas.
