The last 10 years have seen a great leap in the number of truly wealthy people around the world, and while growth is expected over the next decade, the latest Knight Frank Wealth Report forecasts a slowdown in the rate of increase.

In fact, the 10th annual survey found that two-thirds of the 400 private bankers and wealth advisors surveyed said they expect that to be the case.

One of the biggest concerns expressed by respondents, who represent 45,000 ultra-high net worth individuals with at least $30 million each, regards succession and inheritance. More than 60% said their children wouldn’t be encouraged to make their own wealth and about half said they wouldn’t know how to invest properly.

The report detailed the attitudes and trends of the richest of the rich and looked back at the last decade and at what lies ahead. Knight Frank found that charitable activities were expected to grow over the next decade compared with the last 10 years. The main motivation cited for philanthropy was personal fulfillment.
