Not to mention that the 1500 hour limit wouldn't work in europe as there are simply not enough low level flying jobs for those starting out in need of those first hours, they simply would have to pay for most if not all of those hours.
DENTI, you hit the nail on the head!
There simply would not be enough pilots available for the amount of positions on offer in airlines in EASA land if all new entrants would be required to have completed 1500 hours as (unlike FAA land) we do not have a (thriving) accessible market for building the required hours.
Imagine a new pilot with MPL having to fly ~1400 hours SE (predominantly SE as for most this is cheaper) on top of his/her training costs for the possibility to apply to his/her first job, it may take many years, requiring him/her to attend different jobs to sustain his/her hour building experience whilst losing his/her piloting skills so dearly acquired, plus in many parts of EU the weather would only allow him/her to fly such craft in less than 50% of the time...
