Stocks from 2,600 to 4,000, the US Nasdaq from 17,000 to 25,000, gold from 400 to 1,000, Bitcoin from 20,000 to 70,000, silver, and so on—I won't list them all. Too many assets have doubled.

So, may I ask, in real life, if you assume you know ten people around you, how many of them have doubled their assets?
Very few, very few. Why? Because 90% of Chinese people's assets are in their houses, which are declining at a rate of 10% per year.
Everything in society seems prosperous, and you see people getting rich overnight on social media every day, but none of it concerns you.
Clothing, food, housing, and transportation will lock most of a person's funds, and the fastest way for assets to grow is through investment. But then, investment becomes unrelated to you, and the upper class will keep widening the gap with you.
No matter how hard you work, you can't catch up with them.
This is called top-level inflation, bottom-level deflation.
When real estate is no longer in the hands of the lower class, it will keep rising in price; once it falls into the hands of the lower class, it will drop.
And even after the real estate era passes, there will still be other things that lock your cash flow.
Like education, healthcare, and so on.
