This is the graph everyone needs to see for International Workers' Day.

@rbreich
these are all rates of change
all positive values

productivity is increasing exponentially
hourly rates are increasing linearly
And union membership has reached a market saturation?

What is your takeaway

@atreys @rbreich Union membership is on a different scale, axis on the right, showing percentage of workers in a union.
@atreys @rbreich not quite. The Y axis is confusing — but the left side (% change, positive values) applies to wages and productivity. The right side is “% of workers in a union”, and is in the range of 0 to 100%. Line going down==negative change (in percentage).
@atreys @rbreich Yeah, the graph isn't worded particularly well. I'm pretty sure it's supposed to be "percent change since 1950" rather than yearly percent change. We aren't seeing a doubling of average wages year on year after all.
