Companies behave in the job market in any way that they can achieve the quality that is required at the lowest cost. There are always going to be people with wither the means to afford payment themselves, or have worked all hours and strived harder than many of us have ever needed, to save the cash to train. Airlines can therefore have their pick of all those who are qualified to the standards required, whatever their route, and I cannot see how anyone can have a problem with that if the required standards are attained.
Experience in the flightdeck is very much collective - if new staff are paired with experienced captains, I cannot see how there is a problem if those staff are vetted for their basic ability. Furthermore a few thousand hours instructing or flying SEP single pilot give experience in respectively intruction and SEP single pilot ops. Although grasp of CRM in a modern multi-crew cockpit may come more easily to those in the latter situation, inexperienced staff either self-sponsored or airline sponsored will also attain required experience through appropriate cockpit support from senior captains, and adequate structured training. Nobody who walks into an airline environment for the first time, be it with 5,000 hours instruction, or 250 hours from their self-sponsored training has any experience in airline ops.
Your complaint appers not to be from experience, but from the green-eyed monster called jealousy.
There are many routes to the flight deck, but once there we all have to work with each other, so acceptance and appreciation of all the routes taken to achieve this is of fundamental importance. Without such, it is you that will become the liability.
I sympathise with your situation, but if enough people are willing to cough up the 25k, without alterations in employment laws, airlines will act as they choose.
