I totally believe it, which is why my main gripe with the article is that it spends so much time talking about why tipping culture is disrespectful that it essentially glasses over the wage theft it enables.
It also muddies the waters around tipped minimum wage and minimum wage in unhelpful ways. You can see many people in this thread are confused about it.
A more helpful thesis would be tipping leads to wage theft which is bad.
It's also bad because the list price should be the actual price. It only seems normal because all the stores in the US also don't list tax in the price.
