sorry you failed, 0/10.
now go back to the real world check the average change in earnings, it will be less than inflation, so try about 2.5% a year as a pay rise with a notional inflation of 3%, although in real terms for real people it will be a lot higher.
A lot of graduates are seeing no pay rise at the moment and a lot are struggling to get a job. Education gives the country a competitive advantage and improves lives. America is not a good example to follow it has a terrible society and is going bankrupt.
Do you know how much chinese students pay for education? (I don't by the way and would be interested to know)
You appear to be forgetting about job progression as well.
Given that the average salary in 1980 was around £5.7K, and the average salary now is around £25,900, the idea that a greater than 5% per annum increase is flawed suggests no knowledge of history.
Remember, we're talking long term averages, not spot rates during a recession. The actual datapoints for salary between 1980 and 2010 fluctuate, but the overall trend is clear.
