As I understand it the current unemployment calculation counts people who have two jobs twice.

Yes, I've read and heard that many times.

Here in the UK we have two indexes, the Consumer Prices Index (CPI) and the Retail Prices Index (RPI) to measure inflation. Each aim to measure the changes in the cost of buying a 'basket' of products, but they cover different items and differences in formulae used to calculate the inflation rate mean that CPI is often lower than RPI.

Consumer Prices Index CPI forms the basis for the Government's inflation target that the Bank of England's Monetary Policy Committee is required to achieve.

Yes, it is just a deception to the public and also to confuse them.
