The us generally would do 95% in the safe s&p500 and the other 5% in high risk things. The exact numbers varry of course but that is a good rule of thumb for good future growth.

Ok makes sense. But that feels like a strategy Europe could do as well. It doesn’t sound absurd or too risky.

How come we don’t do it?

That is a great question. Also ask why you don't even if nobody else does.

i have some ideas but my insight to europe is limited so I'm at least half wrong.
