There is a multitude of reason why I think mins should be 1500/500 and safety is my number one reason... I was trying to relate my response to the thread... my apologies if you read my post and thought otherwise. Frankly, there are probably 7000+ pilots out there right now that have more than the purposed mins and for at least the first 10 years I don't think there will be a shortage per se. But I think in the long term scheme of things it will be a barrier to entry that less people are willing to make the sacrifice for. I also think the type of experience leading to 1500/500 is equally important.... simply flying around the pattern in Day VFR does not equate to experience in decision making, a sharpening of one's instrument scan, or much needed understanding of Crew Resource Management.
I am a big fan of VFR 135 outfits because it gets you into the thought process of dispatch, weather planning, issues pertaining to pax/cargo, and overall eases the transition to IFR 135/Airline training standards and operations. But all of this is just my opinion so feel free to rip into me if you see some sort of error in my thought process.
