Cost of living index might be a good start but minimum wage jobs are not meant to be permanent jobs imo. As mentioned earlier in this thread, it’s really purchasing power thats important as the cost of labor increases so does the cost of goods and services wiping out raises from an increasing minimum wage. The real challenge is lowering the cost of living (government, tax’s, utilities etc) and offering pathways out of the minimum wage jobs for people that are interested.
I’m supportive of increasing minimum wage but suggest it’s done based on statistics vs campaign slogan. In addition, there must be off-setting triggers for businesses or families that are significantly impacted financially when you increase the minimum wage.
