Yes, I agree with your point. But I was talking about nastier cases of corruption, for example, in certain latin american countries some low-cost airlines between central and south america got approved for operation, some without even satisfying basic requirements, but god forbid small businesses didn't. After some years, these same airlines filed for bankruptcy or got suspended. The kicker? It was discovered they were never profitable, and have since been suspected to be involved in dropping of foreign illegal workers, coming to their destinations as tourists. The most obvious giveaway apart from the latter is that if a carrier is low-cost, it most definitely should have at least a set of profitable domestic flights, and the ones I mentioned above didn't. One of the politicians suspected to be involved (this started under her presidency) is now sitting at the top of a United Nations office.
