Yet these are recognized by straight people as racism, but straight people don’t recognize, let’s be fair, anything at all as discrimination against gay people.
Then looking back, there's IBM who profited by building systems to help Nazis process the Holocaust. And then later built a punch card system for Japanese internment camps in the US, during a time when asians, and Japanese people especially, were highly discriminated against in WW2. People were hurt here for no good reason, and all as an 'economic decision'. In my eyes, IBM is culpable for the atrocities they helped create, even if it was 'just for money'.
Bringing it back to Tinder, the question is why do we need this kind of price discrimination? How is it >consistently< determining that gays, lesbians, and over-30s should be charged more than their younger and hetero counter parts? The key word is consistently, because that feels like targeting. Why not have a flat fee structure, since we're all created equal in the pursuit of a romantic partner? If Tinder wanted to make more money, then just increase the base cost for everyone, not just for certain people in protected classes.
Can anyone imagine if Netflix said, hey we're gonna increase the price for gay and old people by 20%. Like Why? Everyone enjoys watching movies and shows, it's not like gay and older people have more fun watching them than heteros. It's equal enjoyment.
As for a flat fee structure--they're charging more to those they think will be willing to pay more. Either because they can afford more or because they're more desperate. Thus those with better prospects get charged less.
