I have to imagine in several years when you have a wife/husband and kids and ageing parents your views will change.

People always make this case, if you're not satisfied then move. As someone who has changed countries twice and continents once, I can attest it's not an easy or convenient thing to do. Money or lifestyle is one thing, but you're also leaving behind family and culture. Statements like these are so dismissive to that struggle that it's almost offensive to me.
