I have quite a few creative ideas, but am too tired to write them down rn. I’ll go the easy, lazy way (and write about more legislation ideas tomorrow):
Proportional representation like Germany. In every election, the voter votes for an individual and a party. The individual is chosen to represent the riding through STAR voting (my version). After all MPs are elected, to ensure proportional representation according to the party votes (the second vote that voters cast), individuals from party lists are put into parliament.
This way, we get riding representation and party representation.
Hmm. Most of the basic industries would probably pass that margin no problem. I think production vehicles even fall under 10%.
Anything bespoke, from machine tools to Etsy stores, is going to implode overnight, though.
