It reverses it by discriminating against the young, fighting ageism with ageism. I didn't realise age discrimination against those younger that 40 was legal in the US. There are other countries where a "jobs for the old" site would most likely be illegal.
Except it's not jobs just for people who are older, it's companies explicitly saying they do not discriminate based on age. No one is saying they'll only hire someone 40+, unless they're looking for 20+ years experience which implies your age.
