It’s not hypocrisy, it’s another example of a large business using regulation to help stifle smaller competitors.
Starbucks is a huge operation with a large economy of scale. They can afford machinery and business process and inventory systems that smaller competitors can’t. By hiking the minimum wage they are putting pressure on themselves, but even more pressure on the smaller coffee shops around them.
Where ever you see a generous businessman talking about higher wages, look for the following:
1) His competition depends on minimum wage labor.
2) He has a commanding lead in exactly the sort of infrastructure and scale than allows him to minimize the use of such labor.
IOW, he’s a (gasp!) capitalist!
