>Who is claiming that first world women are an untapped source of cheap labor? In what field?
The people who claim that women are discriminated against purely based on gender. If women really are being discriminated based on gender, and companies are hiring less qualified men in favor of more qualified women, then someone should be able to hire up all of the women who are being snubbed by all of the sexist companies and have a competitive advantage over them, right? Same situation with older people, right? Unless of course if this isn't about age or sex. I'm female and not getting any younger by the way. But I still don't buy the bull others try to sell.
>Age discrimination in this context applies to employee hiring.
Are older people better employees or worse? Are they hiring based on age or the other things and age is only an easy thing to blame?
>Is "risk taking" a criteria your company applies when looking for talent?
No startup is a sure thing. Younger people are less risk averse. It's not that a company wants people who will take risks it's that older people want more of a sure thing. They walk in and expect a salary which matches their years of experience, while most places hiring have no use for their experience. Their experience would add no value to their business, and so hiring a younger person who does not demand such a high salary is a better option.
>For one thing, the market can't reward new approaches if no-one tries them.
There is no law keeping the people clamoring about ageism from do that. No one can force others to nor should they be able to. Clearly if they believe that hiring older people is such a good move they should be able to make a lot of money.
I'm unaware of laws which make it harder or impossible for older people to get hired?
