Why are retail investors always trapped?

Please note the following facts:
1. Pension funds cannot lose money and must be profitable
2. Major insurance companies cannot lose money and must be profitable
3. Brokerage firms cannot lose money, or the platform will collapse—without a casino, how can it operate?
4. When companies go public, they raise over 1 trillion yuan each year, draining resources. The secondary market increases by over 100%, adding another trillion yuan, half of which won't come back.
5. Annual stamp duty + 200 billion yuan
6. Private equity, public funds, and QFII funds collectively profit around 200 billion yuan
7. Retail investors' profit margin ( might be less than ), serving as bait, with annual profits of 10 billion yuan.
This is the drain.
The inflow sources are as follows:
1. Social security fund surplus, which is getting smaller
2. Life insurance surplus, also decreasing
3. Retail investors entering the market—the largest source. But the young people born in the 80s and 90s are being drained, and their parents still have some savings for medical needs that can't be touched.
In short, the future of the stock market is becoming like Hong Kong stocks. Many stocks are ignored and considered "penny stocks." Leading companies are pulling the index to new heights.
