My dad spent 30 years in private banking for a big swiss bank, investing money long term for rich people. His advice to me when he retired: The only way to invest money long term and relatively risk free is through property - everything else is just bullshit.
I really believe this is true, from what I've seen around me. That said, bankers and advisors know that this is somehow assumed to be common sense, and quite often use that as an argument to get you onboard investments that are not interesting at all in most cases (apart for them :-).
It's still true - real-estate, by it's nature, is probably a good long-term investment when compared to anything else.
