And the most important _book_ for understanding that _infographic_ is Capital Vol. 1.
It has been said that inflation is not a bad thing because median wages will increase alongside it. In practice that has not been the case. In 2014, when I was asking for $15 an hour, my rent was $740. Now that I'm getting $15 an hour, my rent is $2,400 and I need several room mates just to get by. Inflation is not a bad thing if wages increase in correlation to it, but if they DON'T, then it functions as a tax on our future. The vice is tightening, things are becoming miserable, and a growing number of our children and our future are turning to hard drugs and escapism as a way of coping with it.
The 1% has managed to enslave everyone else; people grow apathetic, and take drugs, because, really at this point, who cares?
The cost of a Big Mac in 1986 was $1.6 according to the Economist's Big Mac Index dataset[0]. The minimum wage in 1986 was $3.35[1] according to the US Department of Labor.
So you could afford at most two Big Macs in 1986, not seven. Also you can definitely afford one big mac with an hour of minimum wage today (minimum wage: $7.25, big mac: $5.36).
