Morno, (similar to Bend a lot) are you aware of the Air Force's training program? Piston engine for flight screening then straight into gas-turbine propeller aeroplanes. So your assumption that one absolutely must learn all about pistons before moving to turbines is highly dubious.
If we were to take the other part of your argument to its logical conclusion then trainee pilots should only be getting their commercial license through an airline scholarship program.
Where do we draw the line?
Like Bend a lot is saying I suspect you have confused a 'loan' for a 'gift'. All we are doing is giving students the scope to follow their talents.
