> And demands of disabled people aren't worth less?

You’re making an implicit argument about the nature of worth. I am using a simplified model based on economic value; if the author has a certain lifestyle that she believes she is entitled to live, and she cannot provide this lifestyle for herself, then the obligation to provide it will necessarily fall on other people. Disability advocacy groups obscure this detail constantly; they want to purchase their dignity using other people’s money.

I think there is a strong case to be made that a just society would be organized around these sorts of principles, but where disability advocates have failed is in wanting to put these obligations on others while resenting the idea that the disabled should even have to show gratitude for the gift they are being given (because this would, in their minds, diminish their dignity). Social justice in the 2010s was built around this idea that marginalized minority groups could treat the majority of the population as workhorses simply because it was considered to be the right thing to do. The model fell apart when people realized they could game the system by claiming marginal status, and also led to a trend of people traditionally tasked with serving as workhorses checking out of the workforce altogether.
