Nowadays, it is very common to see ang mohs living in HDB flats in the heartland. They hold work permits or become PR, make a pile from CPF money and from selling their HDB flats before they balek kampong.
If I were the stinking ang moh, I would also choose SG. Who would want to choose a country without such good privileges like SG? When pappies fall, you can bet all these PR FTsh will also disappear.
