Nobody is willing to state this but it’s pretty clear if you look at the way officials behind the policy talk: they’re OK with this. They don’t mind economic harm. The purpose has nothing to do with protecting workers and everything to do with creating a more ethnically homogenous country.
I think we should all be able to agree that in the limit both sides of this debate are wrong, and therefore what we are arguing here is where the balance is whether this fee helps strike the right balance.
A nation cannot simply open its labour market up to the most qualified workers in the world and not have most of the best job openings going to foreigners. This is simply just a matter of numbers and probability. If you're very skilled already, then you may not see this as a problem, but if you're just coming out of education looking for a skilled job and must compete with the the entire world for a decent job in your own country, you might feel this isn't a great deal.
Similarly, a nation which does not accept any foreign talent, regardless of what those individuals can provide clearly harms that nation's own economic growth potential, and ultimately longer-term that costs everyone.
Maybe some people disagree, but it seems obvious to me that a nation somewhat owes its best jobs to its own citizens, and it should seek to have labour markets which are tight enough that employees will be occasionally incentivised to hire someone fresh out of education and train them up to be able to work high-skilled and well-paid jobs, rather than simply taking the easy option of hiring someone from abroad.
However, sometimes training someone isn't feasible. From time to time a company may really need talent and is simply unable to reasonably train or source that domestically regardless of the salary they might offer. If this is the case then they should of course be welcome to hire foreign workers, but there should be a financial disincentive to this so that companies are always incentivised to first look for workers domestically.
So I must admit I struggle a bit to understand the opposition to this $100k fee. If this causes talent to be lost then the assumption that they are extremely valuable surely must be wrong?
