Your response is full of assumptions. Why would the standard tip increase 75% because it isn't taxed? It makes more sense for tips to decrease because the server will receive a larger percentage of it. You also assume that service jobs will all pay less because tips aren't taxed. Can you provide an example that leads you to assume this? People are paid what they accept. If a business offers less pay, the desirable employees will choose to work for the similar business that pays more money. It is crazy the gymnastics that some of you do to support "your team". We all know that making Over Time tax free is a benefit to the worker. You created a whole scenario that isn't backed up by history or data to make it seem like it is better for OT to be taxed.
There are no examples of what eliminating a tip tax would do because tipping isn't a thing in most countries. At least not the way it is here.
My guess is tip heavy businesses like bars, barber shops, and massage parlors, would suddenly run at or below cost. So instead of paying $25 for a haircut you'll be charged $15 with the "understanding" you'll tip at least another $10. Especially in states where the owner is allowed to withhold a portion of gratuities. Once that loophole gets closed expect the standard to remain.
