You can't effectively counter a list of prices of items whose quality is the same in the 70s and the 10s but whos price is quite different without giving at least a few examples whos price goes in the other direction. It simply doesn't make sense to challenge my methodology as cherry picking, which it was not, without doing the minimum amount of work it would require to check to see if you have any case at all by discovering even one item whos quality has not changed much between the 70s and the 10s but whos price has decreased.
