Beyond that, for Canada Post specifically, I don’t understand why I need lettermail delivered 5x per week. Cut it back to twice per week, and suddenly one worker can deliver to 2.5x as many houses per week

This is how the rich get us:

• "You don't need to see a doctor immediately, you can wait a few weeks" ...and then we have a healthcare crisis
• "You don't need EAs or janitors in schools" ...and then you have an education crisis.
• "You don't need a mental hospital, charities can pick up the slack" ...and then we have a drug crisis.

How about this, uncle moneybags, you don't need to be a multimillionaire, you don't need 14% ROI on everything and you don't need to keep your money after you die. Suddenly we have hospitals, schools and reliable postal delivery and you're just moderately rich instead of obscenely so.
