I doubt this is (potentially illegal) age-based discrimination, more likely it's sexual-market-value-based discrimination. It's easy for Tinder to determine who is or isn't attractive - older men just happen to be at a disadvantage here. It's not Tinder making that choice, it's the women on the platform. Charging more in this case is arguably in the interest of older straight men. The experience of a woman on a dating platform is to get bombarded by hundreds if not thousands of messages. Do you, an affluent man in his best years, want your profile to be drowned by out by hundreds of losers that never stood a chance? One way to mitigate that is to limit exposure to people willing to afford a modest amount of money. Let's face it, if you are old and you can't afford 30+$/month for something as significant as dating, you are not going to find a woman anyway, might as well take you out of the game so as not to annoy the women on the platform with your unsightly presence.
