Key word: average. Always a dangerous - and clickbait friendly - metric.
Keep in mind...
This does not mean the top went up. Let's not be naive, the further you move up the financial / wealth food chain the less price sensitive you are. An increase on the upper end has few consequences.
On the other hand, you can move the bottom up and the average will also increase as increase. This is typically not the first thing that comes to mind but it's a reasonable idea. Unlike the high-end, the low end of the market is very price sensitive. People "living paycheck to paycheck" are far less likely to brush off increases. What happens when they can't make rent? That is The Question.
As things get uglier, those with not much will have nothing to lose. If we don't see voters react this November, they'll be primed for future Novembers. They also might decide that voting isn't going to make a difference. The number of people in this situation is significant. The math is simple.
The rest will be history.
