I have never liked nor really respected the line of argument that says, “I’d leave if I could but I’ve gotten ingrained in life.”
First, Americans are in fact free to go if they want - that’s one reason we’re great! We don’t build walls to keep our people in.
By comparison, most of the rest of the world operates under government that, with all apologies to Chazz palmintieri, can be described as telling its people, “now youse can’t leave.”
Second, consider how many people, all over the world, will, and have, left their homes; families; way of life, etc., usually with just the clothes on their backs, to get to the USA. Considering that, it’s rather, maybe, whiny IMHO, to say “I’d leave if I could but it’d be hard.” Apparently, the US is in fact sufficiently great that many thousands, if not millions, will, in fact, give up all they have just to get here, regardless of how hard it may be to do so. Conversely, if it really was so bad here, people would in fact be fleeing! That they aren’t ought tell us something about how great it is to live in the USA.
