I had to look back at the graph after the explanations so here's the shortest version
"politicians say it's good you've gone from the left line to the right line - an increase in nearly $1000 on average"
"they ignore line 2 in the middle which shows that people went up more than twice as much before coming down again to nearly where they were before"
so while it's true to say there's been an increase, it's equally true to say there has been a massive decrease too.
people who actually have to live like this won't find it helpful to make a comparison to when they had slightly less money when there was a more recent time that they had a lot more money
