I don't think you know what non sequitur means. You're not summarizing the article correctly at all. You're cherry-picking at best.
It's Latin for "does not follow". It doesn't follow that because federal workers get compensated 2% more on average that it amounts to a "redistribution of wealth" and that their wages need to be cut to "redistribute" wealth back to other people.
You're right, the 2% was without the pension benefits, and they get 16% more when pension is included.
2% is nothing. That's a tiny fraction of the COLA difference between even two big cities. And people with a "professional degree" earn 23% less. What is your plan to deal with that discrepancy?
