Yeah, as the article said, one guy states that they'll just push the cost to other consumers - but this isn't cost, it's ridiculous profit margins.
The problem isn't so much the price that they charge people, it's that they cannot substantiate these costs - they're extra profit, pure and simple.
But this is a thing ingrained in US culture, charging additional fees on top of the base fee for anything - I'm thinking of tipping culture as well, which evolved from a "I really appreciate what you did" thank-you, to a "We don't pay our staff enough so we expect you to pay us extra to compensate". Shameful. I'm glad the US seems to have a resurgence of unions and people are standing up to it.
