I think Ryanair are being quite cute with current employment practices for the UK at least, they don't want another Summer like last Summer having to sub in aircraft and crews.
Meanwhile NAS/J2 have adopted the Ostrich school of management position, oblivious as to where the pilot requirements for 2016 will be met from, with NAS back to a 25% planned growth rate in 2016, FR with multiple monthly aircraft deliveries.
Some of this demand will be met from current sand people seeking greener/less brown pastures new, the big problem is basing, Jet2 can't offer anything South of EMA (other than ALC and that more sand) Norwegian can't for now offer anything North of LGW and with a strict base bidding system that means more sand in LPA/TFS for new starters for at least 6 months.
I doubt any (unlikely) increase in money will have any + effect either, home base is key and lets face it with UK infrastructure its easier to commute across Europe than drive between the Liverpool/Manchester and LGW
Even the often rumoured Midlands/Northern bases for NAS would be back filled from LGW based UK commuter and a few in AGP/ALC Euro commuters
