Iirc shouldn't the minimum wage be like 18 bucks and hour if it was keeping track with its historic value in the 60s?
The top economist on the subject, a major advocate of increasing of the minimum wage, and co-author in writting the book on the case for increasing the minimum wage says it should be $12 nationwide as a floor, but higher elsewhere:

For example, David Card of the University of California, Berkeley, and I found that when New Jersey raised its minimum wage from $4.25 to $5.05 an hour in 1992 (or from about $7.25 to $8.60 in today’s dollars), job growth at fast-food restaurants in the state was just as strong as it was at restaurants across the border in Pennsylvania, where the minimum wage remained $4.25 an hour. Equally important — but less well known — within New Jersey, job growth was just as strong at low-wage restaurants that were constrained by the law to raise pay as it was at higher-wage restaurants that were not directly affected by the increase since their workers already earned more than the new minimum.
I am frequently asked, “How high can the minimum wage go without jeopardizing employment of low-wage workers? And at what level would further minimum wage increases result in more job losses than wage gains, lowering the earnings of low-wage workers as a whole?”
Although available research cannot precisely answer these questions, I am confident that a federal minimum wage that rises to around $12 an hour over the next five years or so would not have a meaningful negative effect on United States employment. One reason for this judgment is that around 140 research projects commissioned by Britain’s independent Low Pay Commission have found that the minimum wage “has led to higher than average wage increases for the lowest paid, with little evidence of adverse effects on employment or the economy.” A $12-per-hour minimum wage in the United States phased in over several years would be in the same ballpark as Britain’s minimum wage today.
But $15 an hour is beyond international experience, and could well be counterproductive. Although some high-wage cities and states could probably absorb a $15-an-hour minimum wage with little or no job loss, it is far from clear that the same could be said for every state, city and town in the United States.
