Senior discounts (55+) are quite popular in the USA, although I don't hear young people complaining.

Senior discounts are based on the assumption that this age group is likely to be formed by people who are retired. Similarly, student discounts are intended for full time students that don't have the "expected" source of income that is having a job. I guess Tinder would be ok if they offered student discounts (or senior discounts ;) ). The issue here is whether they can charge 27 year old professionals a different rate than say 30 year old professionals.

That is not a discount for people without a steady source of income. That is potentially a deliberate attempt to skew the demographics of their user base towards younger users (although less of an issue that it would otherwise be, since Tinder without-premium-features remains free to use for 18 year olds, 40 year olds and 109 year olds).

Or maybe those over 28 are willing to pay more, and this is a move to maximize revenue.

This does happen to be the motivation that Tinder stated.

They should be, considering how much baby boomers have screwed over subsequent generations economically.

I see plenty of under-25 offers? e.g. theatre tickets, railcards... (though the latter is also available to students of all ages, but you don't have to be a student to get it, just 25 or under)

In Germany at least, afaict older students can't get the railcard discounts; the terms specify "student (< 27 years old)". I've found that a lot in Europe, unlike in the U.S., where as a late-20s grad student I was perfectly able to get student discounts at most places just by showing a student ID.

Student discounts aren't age based, a pensioner can enrol as a student and get a student discount card, it's dependent on being a student, it's not related to age.

Charging less because someone is young would still be open to an age discrimination case, just as the opposite is true.
