Yes. That's why I said that "68% of people born in the bottom quintile ($20k/household/yr) either stay in that quintile, or do not make it past the 2nd quintile ($40k/household/yr)." (emphasis added.)Income earners are categorized from Red - Green, with red being the lowest income earners and green being the highest. Left to right from lowest income group to highest. 48% of people in the lowest income group are likely to stay there, if they were born within that income group. 27% of people born in the lowest income group are likely to move up in the second quintile, and so on and so forth.
We also know that average income for the quintiles aren't changing significantly -- except, again, for the top 20%, and most of that is because of the top 0.01-5%:
Yes, these charts aren't a perfect proxy for wages, since the top also gets income from assets and rent-seeking activities. Which, uh, poor people can't engage in as they don't have access to that kind of capital. I.e. we are mostly seeing wages as the income source for at least the bottom 3 quintiles, and they've barely budged since the 1960s and 1970s. How are these poor people getting richer again?
"Refrain"Unit Labor cost is intended to track inflation. You don't adjust unit labour cost for inflation. That is statistically invalid. You should really reframe from looking up charts on Google, especially if you don't have a clue of the validity of your source.
As best I can tell, the BLS's calculations for ULC don't use indexed wages. It uses C, rather than RC. Ch. 10, Calculation Procedures, BLS Handbook of Methods
In addition, the annual changes in ULC do not routinely beat the CPIX -- as we'd need to see, if your ULC chart was in real dollars rather than nominal:
There's also a ton of data (including charts I've already posted) that indicates both increases in productivity, and flat income (which in many cases is a valid proxy for wages) for the overwhelming majority of households. I could literally be here all day citing it. Kinda looks like you're going to need more than one FRED graph to overwhelm that.
