Well, yeah. Those companies will pay to send their ad to all middle aged men. Those companies could slice and dice more to get better demographics, but they don't think it's worth it.

Google's business isn't to slice and dice the demographics to show you better ads. It's to slice and dice the demographics in any way that the advertisers will pay for.

Because the people who are willing to pay money are, ultimately, the customers.
