You are really, really stupid, Rectum. Unless that were a log chart (which it is NOT) it is totally meaningless and deceptive. Not to mention 10 years old.
20+ years of food prices: http://www.indexmundi.com/commodities/?commodity=food-price-index&months=300 11 years of gasoline prices: <img src="http://66.70.86.64/ChartServer/ch.gaschart?Country=Canada&Crude=f&Period=132&Areas=USA%20Average,,&Unit=US%20$/G"> A decade of US PPP: http://www.indexmundi.com/g/g.aspx?c=us&v=67
So what is your point? In the 20 year food price link you gave, from 1990 to 2004 food prices were relatively stable, and then shot up and nearly doubled in the last 9 years! Gas prices, almost triple in the time frame you quoted! Not to mention the volatility. So what is it you are trying to get to?
Yes, I know - imagination and looking at things in a new and innovative light - that's the enemy against the establishment. I mean, it's not like that quality actually put this country on the map or anything.
That's OK, moron, I mean, Rectum. Everybody else is keeping up on my corrections for you. So, don't be concerned because I HAVE GOT YOUR BACK, buddy!
