Bullsh!t .... that's complete Bullsh!t. GET THEM OUT OF THE COCKPIT!!!.....it is not unheard of to get a PPL in 60-70 hours, and even in some part 61 programs.....
If you can't get one in 40 hours or less ... you are dense .... you are permanently behind the power curve ... you do NOT belong in the air.
You will NOT like flying with me as Captain with you as a crewmember.
P.S. ... I got mine in < 40 hours ... you HAD to .... FIP circa the '60's ... it was all the NAVY would pay for ...
