You should compare things that didn't change between then and now. BigMac, for example, cost 65c in 1970, and $5 today. Average income (from the first graph) was $3.68k vs $44.2k today. So you had to work x1.5 more time for a bigmac in 1970 than today. A return flight from NY to London cost $550 in 1970, about the same today. So you had to work 10 times more for that flight in 1970 than today.
