MAID is already, IIRC (and my memory is very bad), being suggested to people who can't meaningfully work. They can live rich and valuable lives, but they can't help produce capital, so why not die instead?
Even if I am remembering that wrong and it's not being wielded in the service of capitalist eugenics projects, the system is SET UP for it to be used as eugenics. Like I'm all for assisted suicide as a concept, but it has to be firmly a process FULLY in the control of the person who will die from it, from the beginning to the end. Right now, it's not. It's recommended to. It's signed off on.
So long as outside forces have the first OR the last say, it will always disproportionately have an impact on the people who ACTUALLY could be living well but no, fuck them, we don't want THOSE types.
