Not sure about Australia but Canada would probably include being poor as good enough criteria to approve MAID at some point. Our fucking politicos are already tinkering with the idea doing it for mental people. What would prevent them from going further.

This is actually true for most of the countries. The governments take the biggest cut through the whole process: 1. Sales 2. Approvals 3. Duties 4. Rates

So the higher the prices, the higher their revenue would be. And the inflation caused by that would also in their favor as it virtually diminishes their liabilities. There is no better way of making quick money in short term for the governments, but it will for sure backfire at some point. Those politicians know that, but they cannot care less as long as it doesn't burst in their term.
