Paris has been praised in recent years for their visionary, progressive city-building, but they don’t get enough credit for just being really pragmatic! Everything they’ve been doing is common sense. They’re moving a lot more people with less space while cleaning the air and cooling the city.

“This bill explicitly gives government the power to end legal strikes when a minister decides that a strike is or could become contrary to the national interest — and the national interest is defined solely by the opinion of the minister,” warns top labour leader Bea Bruske. Holy shit. This is bad.

Canada literally has two Conservative parties right now. Conservatives and the extra weird Conservatives. Democracy!
National Post headline (on Yahoo?? For some reason??) by Tristin Hopper (who is a freak!) reads:

"Mark Carney's support surge coming largely from former Conservatives, poll finds"

Opening text of the article reads: "Prime Minister Mark Carney's sustained surge in the polls is coming predominantly from former Conservatives, according to new figures published by the Angus Reid Institute.
According to a new poll published on Thursday, 13 per cent of respondents who voted Conservative in 2025 would now vote for a Carney-led Liberal party if given the chance."

Very cool that Shopify’s CEO thinks the poor should have far less of a vote than the rich. Still worth that ad read money, folks?
Shopify CEO Tobi Lutke says “good system.” In response to the following proposal: 

“Interesting... what about weighted voting proportional to the level of income tax you pay? (no income tax paid - O vote, $1-100k - 1 vote, $100-200k 2 votes and so on... cap it at 5 votes for $500k+. For those that constantly complain about the wealthy not paying tax/fair share they'd have nothing to worry about right? Why not reward representation of taxation and build a democracy around those that foot the bill?”
