And before S&P went from 400 to 7000 largely uninterrupted, and NASDAQ from 350 to 7100. But as those are compounding values (i.e. there is not a linear realationship between year n and year n+1, but an exponential one) one can gain more insights from comparisons of the annual returns - that is the reason why I linked those. The annual returns are not unusual, though. Please have a look at them!

If the prices of assets rise, that is appreciation. If stocks or houses appreciate, you can sell them and profit: Your purchasing power rises. If consumables experience inflation, you can not sell them for a profit: They are either immaterial, like services, or can rot, like food. This isn't pedantry, these are different concepts.

At the end of the day, if consumable prices are the same despite having more pieces of paper to buy them, you did not get inflation.
