If we banned tipping today and Employers did not pay adequately, they would lose a lot of staff.
Today, staff are usually told as part of their hiring conditions that they keep their tips, some in turn tip the other staff. Thus, the employers are encouraged to pay less, and the employee accepts it hoping they will get good tips. As is common with the current tipping model the employer usually always wins, think of the house in a casino.
Yet perhaps counterintuitively, the server positions are highly desired in the restaurant, despite "low pay". Employers are not encouraged to pay less, their pay is already above market. Why should they pay more?
