Just like you, all those business owners are free to protest government action any way they like. You’re free to spend your money anywhere you want.
The business owners however, are stuck competing with suburban restaurants who don’t have to pay an unskilled dishwasher or busser $11 or $15 an hour. Oh, by the way, bar business IS greatly affected by smoking bans. Meanwhile, liquor stores are booming because people are throwing a lot more private parties. Lastly, a mandated minimum wage guarantees that the young and least skilled will find it even harder to find jobs. Mandated minimums and price controls fail every single time.
