Price Rise is inevitable but, not because of evil men. When the cost of supplies, goods and labor rises, business must raise it's prices. Look at my industry. The price of gold has risen drastically since I first opened my store. When I started Gold was $250.00 a Troy Ounce. Now, as I write this, it is $1594.00 and ounce.
Here is a chart showing the price of Gold for the last 10 years.

And if you have any interest check out the spike in Rhodium prices in December of 2007.

It rose over $9,000.00 a Troy ounce in a matter of days.
