Agreed. If you think that setting a minimum amount of experience for a role is discriminatory, wait until you see the entry requirements for most of what we all know as major legacy carriers. Basically, they are usually set up to keep non-nationals away. Fluency in the respective national language, security disclosure which can only be obtained by a citizen or long-term resident of the country and all the likes. All of that leaves you as a pilot with four potential career paths (or a combination thereof):
1 - look for opportunities in your home country
2 - join a multinational company with bases in multiple countries (think Ryanair, Wizz air and all the likes)
3 - look into traditionally expat jobs (think the Middle East and Asia, that's where most of those opportunities are)
4 - become a contractor, plugging up a hole here and another one there, usually short-term (often encountered in corporate aviation, less so in airlines)
Numbers 3 and 4 are only available to experienced pilots. That's the reality of life. You may like it or not, but that's how it is. Not being born, bread and butter in France, you're unlikely to ever get a flight deck job with Air France, let alone a place on their sponsored programme, if and when there is one. The same applies for just about any European flag carrier. Airlines of that calibre never have a shortage of top-notch applicants from their nations, so why would they need expats?
