2% is good, anything over 3% is not good, anything over 4% is bad, 5% and higher is really bad. Hope that clears things up for you.
Can you really say that based only on the inflation? What if wages increased 6%, then 3% inflation wouldn't be as bad as if inflation raised 2% but wages only increased 0.1%? At least if you think about purchasing power I suppose. But won't claim to be an expert on this, happy to be educated by those who are :)
But the bigger issue is that inflation is generally distributed much more evenly than wage increases. Very few employers offer a COLA that is automatic, so wages almost always trail inflationary pressure.
