This is what the Chinese government does when the Chinese stock market collapses, to prevent people from jumping off buildings.

In China people mortgage their homes to dump into stocks at 10x leverage. So when the market collapses >5%, which these days seems to be fairly common, you see a lot of jumpers on the tallest buildings in the city.

The current PE of an average listed company is 300! That's how much of a bubble we're currently in now.
