They may discriminate on recruitment but once you are in, those "zillion young game boys and girls to be exploited" are equally treated compared to their elder colleagues.
So there's no exploitation based on age. Given the EK requirements, you'd better show some respect for those "zillion young game boys and girls" who have a min of 4000 hours, are in their 30-40's, and try to build their life.
I suggest a better analysis, put things in perspective: you will not lose your house because of your age, you may lose it because of your mis-planning.
Make good use of your experience/expertise and good luck.
