Fact is pay to ply schemes do and can lead to employment.
Paying for a common rating and time on type is no worse than earning **** all as an instuctor for a year or two, followed by an excessive bond and a low salary on a rare turboprop used by one operator in the whole of the northern hemisphere.
But accept a bare raring alone will not get you employed, but a rating + aline training scheme; immoral as it is it can and does lead to employment.
