One of the ways the Nazis sold the Aktion T4 programme, which saw disabled, mentally ill, developmentally delayed, blind, and Deaf people, adults and children alike, sterilized at best and outright murdered in a prelude to the death camps in the 1930s was in convincing the German public that there was "life unworthy of life," and that these people were costly, unnecessary burdens on the taxpayers of Germany. Because disabled people couldn't work, so obviously, taxes were paying for them to contribute nothing to society, so it was a far better thing to sterilize the people who could do menial work, to prevent them from passing on their "defective" genes, and for those incapable of work, including infants and children, to be gassed outright. It was only fair, you see. Because they couldn't contribute to society. They were just a drain on the ordinary people who were working to feed and clothe themselves. Why did cripples and lunatics deserve to mooch off of hard-working Germans? Especially during a global depression, when inflation made food and housing impossibly expensive? It was a mercy, you see. They would never have to burden their families with caring for them again. They wouldn't suffer.
Canada is working right out of the Nazi eugenics playbook, down to targeting Indigenous Canadians and other people of colour for state-recommended murder. Because it's far cheaper and far less of a burden on the Canadian taxpayer to just murder disabled people instead of pay for housing, food, and basic needs for survival.
When a government says that paying for disabled and mentally ill people are too expensive to live, then eugenics has won and the only moral option left is to fight back and refuse this deadly, genocidal logic.
