I’m ok with that if the billionaires contribute to the fund in proportion to their “paper wealth” not just available funds on hand.
If you’re worth 5 billion on paper (including stock options, real estate holdings, etc.) you should be contributing to the fund based on that value, not whatever cash you have on hand without selling any stocks, etc.
It also means basic which would preclude living in the most expensive areas of the country. It might mean just enough for shared accommodations and eating a lot of soup in North Ontario while helping to give the black flies a meal supplement.
Either of these is acceptable to me. I really want to vote NDP but they have a messaging problem though I think Jagmeet is a solid guy who was quite personable when I met him.
