I'm not sure which part of the world you are in, but for example in Europe it is common to have 1 month as a minimum notice period, and not uncommon to have 3 or even 6 months (this latter usually if you stay at a company for a long time).
It is also common in certain countries to either get a "reference" letter from previous employers or provide a reference about a person in email or on the phone - going back to 3 or 5 years.
And finally, we are talking about moving countries, if not continents. Maybe if you are 18 you can stop working on a Friday in country A, travel with a suitcase over the weekend and start working on Monday in country B, but as you get older, the number of people and stuff attached to you just grows... and this becomes a rather more difficult and time consuming process.

Hum... If you are on the middle of your life, with all of the responsibilities of the world, this becomes more important, not less.
Get your suitcase and move there, then slowly detach your responsibilities from your previous city. Doing it beforehand just adds a lot of time when everything will break.
Yes, it's hard. The other way around is hard too, and way more risky.
Most likely the US, where at-will employment is the norm. Companies can let you go immediately but you're "obligated" to provide an at-minimum 2 week notice.
OP is stating they don't have to give such notices, so we should change the narrative and treat them the same way we get treated.
