&gt; Chinese companies are the only ones that can serve Chinese customers<p>I don&#x27;t agree with this; but Chinese companies are in a much better position to do so, and China is where the growth is.<p>&gt; Clean energy in 20 years: in 20 years, most of the Chinese rich will have already left<p>A bit hyperbolic; but we already have a global economy. Foreign companies will continue to invest in China (both in companies and in their own projects) regardless of what the Chinese wealthy do. There are 1.2 billion people in China. Most don&#x27;t brush their teeth. Think how much more toothpaste P&amp;G could sell there if people became even moderately wealthy and more concerned about dental hygiene.<p>&gt; large migration from rural to urban: there&#x27;s no jobs waiting for these rural farmers.<p>As long as the Chinese government is willing to sponsor public works projects, there will always be jobs. And China is not unique in the transition from a manual labor to a knowledge labor economy: they&#x27;re actually probably in a better position than most because they can benefit from explosive growth whenever they choose to. And don&#x27;t forget that the Chinese population is aging rapidly: there will be more people exiting the workforce through retirement and death than new entrants into the workforce. Ensuring need and training match up is a problem, but I don&#x27;t think any government has solved that one; so I wouldn&#x27;t call it a huge impediment to their growth.
