FIRE people are funny, I wouldn't retire in belgium even if I was paid for it personally. Do you just order by tax rate and move wherever the number is the smallest ? I never heard of anyone moving to Belgium for anything other than family or cross border workers
Because Belgium didn't have capital gains tax it was actually common to (fake) retire to Belgium for wealthy individuals. There's supposed to be a capital gains tax from 2026 though.
Quality of life for integrated citizens or for FIRE leeches ? The truth from quality of life polls can be far from the truth of migrants on the ground. If you're leaving CA for Belgium to save money and enjoy a nice "quality of life" you're in for a treat lol. People aren't interchangeable units of meat that can be integrated and fully acclimated to new cultures/nations.
I could understand Amsterdam/Berlin for the vibe and the fact that everyone speaks english. Portugal/Spain/Greece/Italy for the weather, the nordic countries for nature and the overall lifestyle... but Belgium, really ? no offence but it's like Luxembourg, if it wasn't for tax reasons nobody would ever willingly move there
