Earlier quoted context omitted.
It is a power issue. Everyone was aware, but the remaining pilots refused to let the authorities do anything. The only reason this is happening is because of Covid-19. No flights, so pilots can't threaten to boycott flying. Let's see if the authorities have enough political capital to follow through with firing them all.
> No flights, so pilots can't threaten to boycott flying. But why would pilots with valid licenses boycott the government preventing pilots with fake licenses from flying? Wouldn't the valid-license pilots want this, because with less of them their salaries will go up? I can't imagine any scenario where people who passed a test would want people who didn't pass it to get the same benefits...?!?!
However, an accountability process that looks into the doing of pilots will get both valid license and invalid license holders in trouble, because I assure you, lots of valid license holders are also doing lots of other illegal things. So, its better as a group to resist all attempts at accountability and reform.
[1] Also, you will be surprised how unambitious most people are. Religion being premier in everyone's life means that they care far more about what happens after they die, rather than trying to improve the life and society they have now. Yes, the irony of having fake licenses being not exactly good for their afterlife is lost on them.
