First, that assumes the company makes no profit at all. Not a sustainable way to keep a company in business. If they go out of business, 400,000 people lose their jobs and a whole lot of them lose their health insurance. Starbucks is pretty well known for being generous with their benefits.
Second, wages are typically only about 2/3 or even less of the total compensation, and don’t account for the employer’s share of payroll taxes.
So figure that you think Starbucks should make half their current profits and give the other half to their employees. That puts it at $6250 per employee, which would likely translate to about $4000/ year before the employees’ portion of taxes, or about a $2/hour raise. Which would be great for employees making maybe $30k/year, but is not exactly going to vault them into the middle class.
Guy I worked with retired from the Navy as a captain and got whatever very generous pay came with that. Then used his veterans preference to get a job in my agency, did that for 20+ years, retired as a gs 14 so he gets that annuity plus his TSP savings plus social security in a few years. He’s still barely 60, so he is working as a consultant. I’m guessing he’s pulling down $200k with all the various incomes and maybe working 20 hours a week, and he’s got the Healthcare and other benefits for life. People trash talk the military and government but if you work the system right it can be worthwhile. Hell, I wish I’d joined just so I could get USAA.
