Also, $70K is absolutely terrible in Seattle. I don't know why everyone applauded. He was massively underpaying most employees before and still did after.
Sure, but his company is a credit card processing company, so there are probably a lot of tech workers.
I mean, a quick look at Glassdoor will show that while they do pay their "minimum" wage workers (which is probably an incredibly small part of their employees given the industry it's in) way above market, they underpay the rest and it is mentioned in almost all the negative reviews.
Sounds like they/he decided to pay their workers more evenly across the different roles. That choice would be internally consistent and desirable for some.
