They are not. Productivity is the key.
And why should wage increases be inflationary?
Wage increases raise the costs of peoduction so prices go up. Prices going up results in inflation, whether a small amount or large, depending on, in this case, the amounts and the widespreadness of the wage increases.
The inflation started when unskilled classes of workers doubled and tripled their wages, but not real production.
That is inflationary. One cannot raise the bottom 30% of worker wages and not have an inflationary reaction.
Cost of a Big Mac theory.
