// as wages rise so do production costs and hence prices which leaves the man on the production line no better off //
The general trend in the private sector is that pay awards are subject to how the company has performed! Invariably a company that has underperformed (to the dismay of its employees) will probably announce a pay freeze. In a company where business has thrived in a given year, it may choose to offer wage increases in line or above inflation. In either of the above scenarios, this does not necessarily mean production costs will increase.
Is it not reasonable then, to suggest that companies to remain competitive, they do not want to be seen, passing on rising costs to their customer base. Therefore every effort is made to stem the rise in production costs.
