Bud, Canada has that, it's called Medical Assistance in Dying and it literally functions as a eugenics tool since disabled people opt for it due to the insufficient social welfare support for them.
Liberalism is capitalism, BTW, despite colloquial uses of the word "liberal." MAID was seen as "progressive," (often synonymous with "liberal") and its stated principles are not consistent with its function under a liberal system because that system is antithetical to valuing human life.
Edit: any other lib that comes along this and agrees with this person, read below and see how they try to argue that race is a real, genetic thing, and that this means that diseases or disorders that are prevalent across humanity aren't hereditary. So like, I don't know what better evidence I could produce to show you how liberalism has latent white supremacy and eugenics.
