A little while back in another thread, someone was arguing that the only way to force the US away from tipping was to not tip. That is just...that's not going to work.
Okay, let's say that enough people stopped tipping servers to the point that the employers have to start making up the difference to pay them minimum wage. Then what? Small businesses already operating on a thin margin close. Chains raise prices. Previously tipped workers probably make less than half of what they did previously. And the government? They do nothing because, heck, everyone is getting paid enough. Because we all know that US minimum wage is definitely something people can live on.
Increased prices and closing of some small businesses seems inevitable no matter how you go about it, but we can't just rely on restaurants paying servers up to $7.25 an hour and expecting them to survive. It's a massive change and needs to come from the top down. And I can't see that happening.
