Good reviews and pay what you want do not feed families and make ends meet. It would not work.
So you want to start a butcher organization?
Mr. Butcher: Hi Mr. Cattle...I'd like to start a butcher organization
Mr. Cattle: Oh, that's really great! Where do you plan on starting it?
Mr. Butcher: Vegetarian City
Mr. Cattle: No cows for you
Fail, let's try again.
Mr. Butcher: Hi Mr. Cattle...I'd like to start a butcher organization
Mr. Cattle: Oh, that's really great! Where do you plan on starting it?
Mr. Butcher: Meat Lovers Heaven
Mr. Cattle: If you'd done your homework you'd know that I'm already invested in 10 butcher organizations there. No cows for you.
Fail, let's try again.
Mr. Butcher: Hi Mr. Cattle...I'd like to start a butcher organization
Mr. Cattle: Oh, that's really great! Where do you plan on starting it?
Mr. Butcher: Meat Lovers Paradise
Mr. Cattle: Great! I'm going to invest 10 cows in your organization. *hands Mr. Butcher 10 cows*
1 month later
Mr. Butcher: Here's a ton of positive feedback *hands Mr. Cattle a lot of money*
Mr. Cattle: Thanks! Have 20 cows! *hands Mr. Butcher 20 cows*
See...Mr. Cattle has cows to give because he doesn't waste his cows. He invests them wisely. Maybe not always, but more often than his competitors. If it turns out that you're one of the exceptions...if you waste the meat...then you're not going to receive a lot of positive feedback (money) from consumers...and Mr. Cattle is going to cut his loses.
The thing is...it sounds like you're imagining an extensive free-rider problem. Is the free-rider problem going to be so bad that nobody's going to want to give enough positive feedback (money) to the butchers? As a result, we're all going to become vegetarians?
Ok, here's my theory. If you think the free-rider problem is a serious and genuine problem...then with our current system...you'd probably be happy with a 60% tax rate. Am I close?
