I don't understand why the extended stay brands earn less per $. It's not likely those are any cheaper than other brands (except for higher end/luxury brands). I personally value having a refrigerator and a microwave on vacations, so I end up choosing the extended stay brands more often.

I agree with you. It has always been that way. I guess when the brands were originally introduced they were mainly used for longer stays and the complimentary food was more substantial (e.g. full dinner almost every night in addition to breakfast). So the rationale for the value prop I guess is you got more in return for your money so less points. Even pre-covid, the current food options are greatly reduced (light dinner/heavy snacks three nights a week). I also think many folks use these hotels for shorter stays. They should align the points earnings with the other Marriott brands to 10 points/dollar to reflect the current value prop. Doubt it will happen.
I don't keep as up to date on Hilton nor IHG but I believe they also have reduced earning per dollar for their extended stay brands. I.e. this seems to be an industrywide practice and not unique to Marriott.

P.S. For family trips, I am frequently redeeming points rather than earning them. I too like RI for those trips and the points/dollar is not relevant on award stays.
