It sounds like you just don't like parliamentary systems? If voters don't like the party leader, they still have recourse to select other MPs in the upcoming election in a month, right?
As a lifelong student of politics, I think there are trade-offs to presidential vs parliamentary systems. As an American experiencing political gridlock in the US Congress across decades, there have been times I have been envious of the notion of having a legislative and executive branch work together rather than in diametric opposition.
Edit: Also, while I believe Carney is friends with billionaires, his net worth is around $7 million. For someone who spent so much time in investment banking, to my American eyes that doesn't seem extravagant. Compare to former presidential candidates Mitt Romney, net worth of $186 million.
Big agree. Figuring out over building with the interface was so frustrating! Seeing city connectivity too.
