In earning, you must be real, that is why people use to say real
wages, if the inflation is 5.5% as of today, and your earning goes
up only 3%, then you are still at negative position, it will
be a joke if you tell people that my wages had increased.
Real wage increase should be 8.5% inorder for you to cooling say
that my wages or earning had increased, otherwise, by next year and
so on, with another inflation figure coming out, you will be
far far behind the chasing pack in a so called first world society
taking a third world earning.
