Hobo, All I can say is that my home town had mass emigration and during the 1950s when I started out at as a 17 year old, I can vouch for the fact that the men and boys from my town were not old or young `lags` just honest people in search of work.
I think you are referring to a very small minority when you suggest that they had `problems, I would suggest too minute to consider as a factor in the problems they brought on themselves in their new homeland.
