Small businesses are privately held and don't publish their numbers. I do work for a company that manufactures products, sells them wholesale, and has its own retail locations and know that COGS will always be around 50% of retail costs.

I really don't care about PP but you brought it up and made an inference that is beloved by conspiracy theorists but is unfounded.

Dismissing researchers because you don't agree with them and think they have a secret agenda when you have no idea what they said or how they approached the problem is poor thinking. Scientists and economists are focused on expanding human knowledge and understanding more than political positions. The UW researchers and economists have data to back them up. If they're drawing conclusions from a flawed approach, or intentionally misrepresenting the data to support their views then they've opened themselves up to criticism from their peers and their academic reputations are on the line. Throwing your hands up in the air and saying anyone who claims to know anything until the wage increase is fully implemented is naive. At this point they've shown that a 10% raise in hourly minimum wage hasn't crashed the local economy. There are a few more increases coming and if employment or businesses are harmed then the researchers will be able to determine what levels of pay increase are sustainable. They'll do additional research to rule out other causes for the downturn, and someone will study whether the downturn is due to wage differentials between Seattle and outlying areas.
