Flex, in the USA, they are NOT doing that. You have highlighted the big problem with working for CX: they can hire from anywhere, at whatever standard, for whatever pay. They will ALWAYS be able to undermine your pay and conditions if the management of the day is willing to scrape the barrel. That is all you need to focus on. If you don't want a career that is constantly subject to that threat, then endeavor to establish a career with a first world airline. There really is no other choice. In the meantime, enjoy the spectacle of CX losing all it's experienced and qualified crew. The day will come when CX is JAFAA (and it is almost to that point already).
