I am not from the US, so this "protestant work ethics" sound foreign to me. And to be honest, very harmful.

Measuring someone's worth by their productivity sounds incredibly misanthropic, to a cartoonish degree. It's part of the same societal illness that only considers something worthy when it has a monetary value. Looking at some responses to your post (that should be very uncontroversial) is an interesting experience in that regard.

Luckily I don't have any disabilities, but I pity those that do. I think that society has a duty to help the less fortunate. That should be an uncontroversial stance too, but oh well
