Explanation:

Based on the information given in the question, we should note that the real interest rate is calculated as:

= Nominal interest rate - inflation rate

In this case, the real interest rate will then be:

= 3% - 5%

= -2%

Real change in income = -2%

Nominal change in income = 3%

The tendency that is leading people to feel like the pay decrease is unfair is the money illusion. This simply means that rather than thinking of money based on its purchasing power, that is in real terms, one thinks of it in nominal term which is in its far value form.
