I’d like to see a multi-phase federal plan with the clearly stated ultimate goal to phase out tips. This plan should have clearly defined beginning, milestones, and end so that workers and businesses could plan around it and everyone would be on the same-ish page or at least know what’s going on.
Stop taxing tips on specific jobs/industries combined with bringing up the minimum wage for all workers to standard (no $2.50/hr wage for tipped waiters, etc).
Start an educational program that talks about the history and effects of tipping culture and why this program is good to try to stop it
Start a government program that encourages reduced tipping, promoting specific percentages (e.g. 10% for restaurant table service) to consciously try to move the culture, this should go along with an increase in minimum wage that effectively makes up for the reduced tip. Repeat this step if needed to slowly step-down from tipping culture into one based on labor appropriately compensated by the employers.
This will help people know what to expect on both sides of transactions
This can reduce negative feelings associated with not giving a large tip because you know this is all part of a plan and the employer is expected be following the law and increasing compensation.
This will provide cover for business to increase their prices accordingly, and simultaneously the government can put out guidance about how much prices should be expected to rise and how your total bill won’t really change much.
The end goals should be clearly stated, something like
A person working 40 hours/wk at minimum wage should be able to afford a basic, clean, up-to-standard 1-bedroom apartment, food, and transport, and basic medical care.
Hopefully, culturally, tipping changes to be seen as like " ‘the old way’, weird old people like paying service workers to feel superior".
