Fair enough.
If you look at the weath distribution numbers it's quite a big "some" (not per person compared with those few people that hoarded lots of weath, but because it's still quite a difference between generations and there are A LOT of old people, so it adds up), mainly because it's old people who outright own the houses were they live which are worth a lot of money per current day house prices.
Because it was those very same (now old) people who voted for the very house inflation that's shafting the young and made them relativelly much wealthier than the young generations, they deserve a lot (so, a very large "some") of the blame.
