This is a minor annoyance only to foreigners here on vacation. You quickly adjust to not having the tax included and it is something people in the US don't even consider unless they've traveled abroad. The system with the taxes included in the advertised price only really works when you have a national tax with no other taxes involved. No state or city will ever go for that and it really isn't bothering anyone since everyone is used to the system already.

If you want to rail against hidden charges complain about the restaurant welfare system that allows employers to legally under pay and fire employees for not making the majority of their money from tips

Dragging this back towards a HN topic, years back this caused a fight for PC computers stores. They argued that their main customers were businesses and so advertising prices "before tax" was expected by the trade customers. Others argued really most customers were hobbyists and so would pay the VAT price.

Obviously it's beneficial to be able to advertise the lower price, these days assembling your own PC from components must be much less common than it was back then so I imagine even if the decision went in their favour back then that's changed since.
