Wiggy actually put it far more diplomatically than I would. No doubt, if you have the money and the time, you can be thick as a brick and by sheer rote learning, eventually qualify to be a pilot.
This is the greatest danger with pay-to-fly. I could give a classic example of this. Of someone flying as F/O on medium jets with an international operator right now. Absolutely unsuited to the task. But the person would be so easily recognised by some, that to elaborate further with first-hand horror stories about this guy would probably invite a lawsuit from his Daddy's lawyers.
Unscrupulous managements will move the goal posts out as wide as they need to be to capture p2f pilots with not much more than a pulse to fill the right seat. The crunch will come (literally) when they run out of competent commanders.
