In the case of the Chinese, it is better than holding cash in the long term. I can think of a whole host of reasons why buying real estate, even without rents would be a safe avenue for cash. Not necessarily the best, like rentable property, but that isn't the point. Nor have I found that the Chinese are really good at investing anything.
Think of them like trailer trash that won the lottery. You can take the person from the trailer, but never take the trailer out of the person. Many Chinese didn't grow up with business savy parent, or peers. Many of them are millionaires or billionaires through cronyism and not so much because they produced something of value. So they are still learning, or relying on what others told them to do. Real estate in the form of just buying property is a semi-liquid asset with gains and losses easy to understand.
My wife's cousin had a business a few years back where they would help Russian billionaires spend their money in the US. I mean, how many leather Prado sport coats and Rolexes can you own right? I thought the whole idea was absurd. Here you had a guy who made his own millions through hard work, business savy and investments teaching new Russian millionaires and billionaires how to spend their money. And most of it was spent on garbage. YOU EVER SEE THOSE WEIRD DIRECT TV COMMERICALS.
There you go. True to form.
Because they didn't earn that money, they were often bureaucrats or children of bureaucrats who were at the right level when communism fell and were able to sell state assets or control state assets for their own benefit. This is how many of the oligarchs came to be. So many of them are still no smarter than mid level bureaucrats at places like your local utility, DMV, or even Federal Gov't agriculture co-op. Yet now have millions or billions to play with and no sense of real value.
"In the world I see you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Towers. And when you look down, you'll see tiny figures pounding corn, laying stripes of venison on the empty car pool lane of some abandoned superhighway." T Durden
