Do not intervene
Yes, do intervene
So "outsourcing is actually good for low income workers" is a less than true concept when at the end of the day they end up paying MORE to open cans than they did when they made more money and can openers cost more.
Peoples behavior doesn't make it any less false economy.
You might have a point if people's money supply wasn't a constantly regenerating thing. People keep getting paid. They have a continually limited supply of money that gets resupplied on a regular basis. That's how virtually everyone thinks. I don't think that I can buy a cheap car today that might only last 10 years, or an expensive car today that might last 20 years. I still only have a certain amount of money to spend today, I'll get more in 2 weeks and more 2 weeks after that. Most people, like it or not, don't think over the long term. False economy or not, it is the economy we have.
