I think it's a point in favour of any pilot. Who can forecast the shape of the industry in 20 years time? Will the legacy carriers survive? There is no guarantee that they will, and if they don't those currently employed them will find themselves back at the bottom of the pile and trapped there by the seniority system. The freedom to choose one's own destiny is a very basic and valuable one and can not be left in the hands of anyone else but the individual.
