wrt experienced pilots, there's no question we are back on a downturn after several exceptional years. Over the last 12-18 months I am sure some airlines were taking "experienced" pilots on who in normal circumstances they wouldn't touch with a bargepole, plus some sectors eg; experienced TRI/TREs were very hard to find, and some were making ridiculous money with airlines fighting for their services.
There always seems to be a surplus of newbie low hours pilots who, lemming-like, march on to their "destiny" (be it the 50% who get a commercial job or the other 50%), ignoring economic and airline reality. If you look at India recently which was effectively closed to foreign F/Os, within an incredibly short time there is a massive overload of Indian wannabees (many badly trained) fighting with each other to get into the right hand seat. Some of them were saying to me 2 years ago that there was "no way" they would start flying an ATR, they only wanted a jet job when they finished training.
There is the odd country like the former USSR where there is a chronic shortage of local pilots through specific circumstances, but it's very much the exception.
