So, Dow goes from 10,000 in 2007 to 20,000 in 2017 (appx), that works out to about 7% annual return, compounded.  It is less for the TSX, so let's say 4% annual return. 

That far outstrips inflation. 

On top of that, the yield on my portfolio is just under 5%.  That is almost a 13% annual return.  (9% TSX)

A little more than inflation I think.
