rising prices

Well being well informed of what is happening in France, I am aware of the rising prices and the stagnant salaries.
To fill you in, France has about a 9% rate of jobless people and the people's with job's salaries are going up at a ridiculous rate while the market has been inflating quite alot since the Euro.
I am wondering where this is going to go, not too long ago i heard of rising rice prices. For many people in third world countries, rice is the cheapest and most available resource to eat. But now, because many of them are poor, they will not be able to buy as much.
Down in the US this type of price rise can also be related to. Simply look at the price of a juice, the cheapest (1.5 liter bottle) is well over 4 dollars, and this is not high quality juice we are talking about. Its not just juice prices going up, its fruit prices...
If these prices continue to rise everywhere in the country, the poor will become poorer, the middle class will have more problems living but the rich will stay, well, rich.
