Okay to service the labour market you can have -
Assume that Indians are superior on the merit. So in a open labour market they will end up coming on top. And that is what exactly is the situation with GCC/KSA. This explains why Indians dominate the labour market and as a result India earns from Saudia Arabia, UAE etc nearly $50 billion every year in remittances.
But if this is about merit why do we have the farce of 'brothers' with KSA or GCC? I have brothers and trust me I give them 'preferance' over outsiders. I don't apply the 'merit' template on them. To illustrate my point let's all accept that Indian workers are superior and win on merit. Well, I can tell you Indian workers are also superior to drunk Poles who are far more expensive then Indians. Why not try to get to sell your workers to Western Europe on merit against Poles, Slovaks, Romanians? I need to add a small extention to my house and pave the driveway. I am pretty confident that a bunch of sardars from Indian Punjab could do the job for £5,000. The Poles cost £25,000 which is still cheaper then British builders. Trust me there is no way those sardars would be legally allowed despite their merit. The Poles or Slovaks have been given legal preferance.
Allow Indian workers on merit? Nah ....
