Having someone pay to perform labour that would otherwise be remunerated should be illegal. And this is exactly my point.
You are not only not making money,
not only working for free,
But on top of it Having to pay to work!
Once you have:
1. Paid for your licences
2. Paid for your Type Rating
3. Paid for your line experience
You will not get hired because now you will cost airlines money. Now they will have to finally pay you for your services and why should they, there are plenty of other free pilots from where you came from.
Now you are in the middle. You have more too much experience to be a new entry (meaning free pilot),
But too little experience to be a captain (A legal and expensive requirement companies have yet to be able to by-pass)
What now?...catch 22!
Free labor should be out-lawed straight-out.
