Christ I don't know how you look at that without being disgusted unless you are literally just seeing a line go up and stopping all thought processes at that.
That is a 40 year period with a net increase of $50 per week.
The inflation from 1980 to now averages about 3% per year or a cumulative 270+% in those 40 years.
The purchasing power of $315 in 1980 is equivalent to roughly $1,300 today (and it's technically more based on metrics).
So us making $365 today means we are getting the equivalent of a pay reduction to $90 in 1980 or a drop of 72% of our pay
The average American is making ~28% of what an equivalent job would be in 1980!
No we aren't better off. I don't know how you couldn't be sickened by that.
