Yes but at that time foreign powers where not using immigration as a weapon. There where not NGO's that plan mass immigration, cards and phones for those who come, lawyers for papers and so on. Usually poor Europeans would take a ship pay for it, being treated like cattle and disinfected with DDT , receive no welfare at all. A different picture. And if we want to go to the founding fathers time, you were not even sure to survive the trip and then would face the unknown with zero help. How many would come today in that condition? Zero.
