Lol 5-13% inflation? Um, try the vast majority of the last 20 years inflation as been somewhere between 1-4%. Source ( http://inflationdata.com/Infla... ) 1-4% is a healthy range for an economy, if it is below or above bad things will happen (Deflation on the low side, runaway inflation on the other end). Deflation causes people to sit on their money, not invest in new tech, not invest in the future and not expand their businesses (who wants to expand when the money used to do so would be worth more then the investment made?).
A zero percent inflation rate is unattainable (population growth, a million other factors) so keeping it around and low in the 1-4 range is good for everybody.
