Is it the bottom?

The graph shows the fall in wage income relative to the rise in prices. We see a rapid decline in the income of citizens. Perhaps this is the effect of the January holidays, because. salaries haven’t yet arrived at the bank and therefore the 3rd week of January is the most depressing. This trend was observed in the period 1979-1981, and it was the bottom of social sentiment. There is one difference - in the past it coincided with the bottom in the stock markets, now, in our opinion, we haven’t reached it.

What conclusion can be drawn from these statistics?
