People want to migrate for different reasons. For the price of
your HDB flat and your car you'll probably be able to afford a
nicer house and a nicer car elsewhere. With that car you can drive
up to a nearby vineyard, enjoy the scenery and grab some wine.
Thereafter you have the option of going fishing with your buddies
where the view is nice and the fishes plentiful and big. In
between, you guys talk cock and drink relatively inexpensive
alcoholic beverages like beer and wine. Inexpensive because, they
are produced locally and others probably don't tax as high as
Singapore.
I'm contented in Singapore, you can say that i am happy staying
here but its not Utopia. I do have my gripes but i'm not living in
conditions that bad that only by leaving do i have a spine, feel
liberated, feel less silly etc.
There are several ways to migrate, its no big deal.
