-------Sure, it's a pain to pay more for something, but some perspective is in order, as you provided, and also listed below:
$6.50/gallon for designer water with a French-sounding name
$5/gallon store-brand orange juice
$3/gallon store-brand milk
$9.50/gallon cheap wine (the kind you can buy by the gallon)
$650/gallon decent champagne
Perhaps the most salient perspective is that gas is available.
For a child of the 60s, you sure must do a lot of driving. I put about 5 gallons every week in my '88 Sentra with it's 116,000 miles and all. I buy at least that much in milk and OJ at the grocery every week for the family. I'm out about $19 for milk and OJ, about $10 for gasoline. So gasoline isn't all that big of a part of my weekly budget. 20 gallons of gasoline each week seems like a lot of driving miles for a '60s-type person.
