What class are you?

There is a nice website which tells you what class you are according to a number of factors. Apparently there are 5 classes: upper fifth, upper middle class, middle class, lower middle class and bottom fifth. The factors they used to determine your class are factors such as occupation, education, income and wealth. Check out your class by clicking on here. My results were as follows:
Occupation
my occupation places me in the upper middle class range
Education
my education, I have a Bachelor's degree places me in the top fifth
Income
my income for the year 2007 places me in the middle class
Wealth
my wealth or my savings if you like which I only started this year places me lower middle class
Average
All in all it makes out that I am Upper Middle though I think I am more Middle
