> Today, tipped workers in the US are paid, but have a lower minimum wage than normal workers.
No, they have the same minimum wage as all workers. The employer is liable to pay the employee if tips + earnings from tipped min wage are less than earnings from non tipped minimum wage.
That's true on paper, but I worked as a server for like 12 years and never heard of it happening once. In contrast, I've had like 4 bosses who practiced wage theft.
