A real humanitarian would say why not $10,000 an hour, but we’ll start with PF Whalen’s modest proposal. From PF Whalen at bluestateconservative.com:

The periodic debate regarding raising the minimum wage has resurfaced once again, only this time the argument is connected to the larger discussion surrounding a sprawling, $1.9 trillion COVID relief bill; for some inexplicable reason. In the bill unveiled by House Democrats last Friday, if passed, the minimum wage would increase incrementally from the current $7.25 per hour to $9.50 per hour this year, and eventually escalate to $15 per hour by 2025. Prominent Democrats across the board have supported the idea, including President Joe Biden.
If we deep-dive the issue in trying to understand its full impact, we can learn a great deal about the pros and cons of increasing the minimum wage; particularly with the cons. But there are two pieces of information that are difficult to come by. How, specifically, did we arrive at the number of $15? And, based on the Democrats’ reluctance to acknowledge the negative impacts of a minimum wage increase, why don’t we just add a zero to the number and increase the minimum wage to $150 per hour?
Sen. Bernie Sanders (I-VT) was the first influential public figure to float the idea of a $15 minimum wage, having proposed the idea all the way back in 2015. Sanders’ plan pointed out his perceived benefits for those who are being paid the minimum wage. Beneficiaries would see an improved standard of living; the burden on taxpayers from food stamps and Medicaid would be reduced; and an increase in available income would spur economic growth. It sounds like a wonderful plan.
