Were they punished for attempting? Should they have been? This is America, after all.
Apples and oranges PP. Ellis island was for LEGAL aliens, the government actively sought labor from other countries and they used work permits and even land deeds as a carrot to bring the people here.
What's going on now is unacceptable. More than 10% of a nation lives illegally within our nation. It's bad for the US (except the business owners who make tons of money) and it's bad for Mexico. Instead of investing in schools, hospitals and factories they're relying on remittances the illegal workers send back home.
You mentioned 2 categories of immigrants but if only 10% of the illegals commit a series crime than who's paying for it? The business owners? Nope, as always we, the taxpayers do. Who's paying for the numerous child births, prenatal care costs, vitamin supplements, etc., etc? The business owners? Nope, the taxpayers do. (Latinos have higher child birth rates than most muslim countries, they definitely put Poland to shame.)
What about the thieves, the gang hoodlums, the drug smugglers and the dealers, the maffia hire-to-kill murderers and the rapists? Do the business owners pay for the costs of their prosecution and incarceration? (won't even mention the human cost the victims have to endure). Nope, the taxpayers pay... The vast majority of gang members in the California, Arizona but also North Carolina and Alaska prisons belong now to Latin Kings, the Mexican Maffia, MS-13 and other Latino gangs. Who's paying the costs of keeping those thugs in prisons? The business owners? Nope, it's you and I.
Illegal immigration hurts this country even if most of the immigrants are "honest and hardworking" people as you describe it. (and I agree with that description)
Don't be fooled by the "poor Mexico" mantra. In 2006 Mexico was the 6th largest producer of oil in the world. Their corruption is killing them from within and the worker drain to the US only make things worst.
1st offense 1 month in prison plus a large fine, second offense 5 years in prison that can be waived by your embassy paying a $1,000,000 fine. I bet you Mexico would beef up their border enforcement prompto once we started collecting the illegal immigration fees. Also, non-neighboring countries would let the fine to be paid by the offender and this illegal immigration fiasco would end sooner rather than later.
