People are starting to see one of the weaknesses in the ETP:
SUPPLY and demand is the foundation of any market economy. If people want more of a certain goods or service than what is available, then prices will rise.
The opposite happens when there is too much supply, as that will lead to a fall in price.
The same thing is also happening in the labour market. Supply and demand mechanics work the same in that market and like how prices fluctuate according to the pull and push of demand and supply, wages react in the same way.
The thing with brain drain is that people say it is hurting the economy. Yes, it is, but the migration of labour is also a good thing that has happened for workers in the country.
Without it, the supply of skilled workers will be more than it is now. And when there is a lot of something, prices remain sticky to the upside...
