We are in a world that is driven by money printing and, in general, I believe the standards of living for many people in the Western world will continue to decline as they have declined over the last 20 years, if we look at median income in real terms.
How the world will look in 5 or 10 you and I and nobody knows, although some people think they know.
So my advice is to be diversified. Hold some real estate, stocks, bonds and gold and you have to also diversify your assets geographically – don't hold everything in the US. Hold some outside the US as well; hold some outside Germany, outside Switzerland. You have to be diversified. Then you have to hope for the best.
