The delicate balance of immigrants

Much talk has been about foreign talent, immigrants, foreign labour. There are two schools of thoughts:
1) in a highly globalized world where movement is very fluid, it is normal for people to move around. In a highly globalized world where competition is tough, companies pay to attract the best. With better pay package, people move.

In a tight labour market, foreign labour is needed to ease the labour crunch. It has always been Singapore's rationale, if we do not embrace foreign talents/immigrants/labour, our economy will not be able to get to where it is today.

Singapore is not alone. Critics in Britain are saying that tightening foreigner influx will be a big barrier to growth. Even Germany is attracting foreign professionals with its own programme.

2) however, the other school of thought is: locals are saying no to foreign talent because they push up cost of living.
Dynamics change when new things are introduced. In science experiments, when new element is added, there would be some chemical reaction and perhaps a new compound is formed.

So I do not have the solution to find that delicate balance between attracting and restricting foreign talents. I'm just an ordinary citizen who needs to find my own balance in this globalization wave.
