It depends how intelligent, enterprising and educated you are.
Any dullard can rock up to a flight school, buy an ATPL, by and large find a job (at least in a good recuiting climate), and by and large, get upgraded when their time comes. So for them, the pay is good compared to labouring, or low grade office work (although guys who dig the road can earn £60k+, esp if they do overtime. No capital outlay required either. No jet lag, or being away from their families for days on end)
For anyone with anything between their ears, aviation is an exceptionally poor career, IMHO. 40 years of being treated as a unit of labour, nothing more - often less. Very little scope for performance related career advancement - you get paid what it says on your payscale, whether you are an conscientious ace, or a borderline slacker.
