The solutions are tough trade offs: One of the solutions is to make deals with their country of origin to serve time in jails back home, tighter border control to stop “theft thieves” from entering and prohibiting begging again as the Eastern European mafia bring in beggars to serve as mules. Especially the one around begging feels culturally difficult and it makes people sad to have to prohibit begging again as it was legalized a couple of decades ago.
Do they pay them more than typical software developer salary is in Eastern Europe? Asking for a friend.
