Wilcom, I'm just spitballing here but my thought is that since beef is sold by the pound (not kilo, just a good old 16 oz. avoirdupois) a thicker cut of meat would cost proportionately more. Average for a good rib eye will go for an average of $8 - $10/pound. To feed a family of four would require a minimum of two steaks. A lot of family budgets cannot tolerate that expense. Cut it thinner and you think you're getting a better deal, but really not.
On the other hand, if you go to a decent restaurant the steaks will be cut on the thicker side. Most of the supermarket chains such as Kroger, Tom Thumb/Randalls, Albertsons, HEB, are not noted for good beef. Go to a decent meat market and you will probably be happier.
And for my good Aussie friends, don't you think your comments are a tad condescending? Comparing a state of the union to an entire nation is not exactly a valid comparison. [smiley=beehive.gif]
