What is a fair wage to business and what would be the change in that answer 5, 10, 15 years down the road with no union or collective barganing abilities? That's the real question bubba and you're delusional if you paint a pretty picture for the workers.
Do you want the truth or do you want feel good nonsense?
The reality is that a worker who does not add value or skills cannot expect automatic raises just because of time spent there.
In private business, certain jobs have a certain values placed on them and thats that. For example - a assistant secretary is never going to make 100k a year, whether shes been there for 1 year or 100 years. Private business, unlike the govt, is accountable to reality.
Second, if you want another culprit, look at the devaluation of the dollar. We dont have nearly the same purcahsing power and the same wages do not go as far. But guess what? Most small businesses do not make huges amounts of money and cant afford to keep increasing wages to offset the inflation and destruction of the dollar.
If a person wants higher wages, they have to improve their skills and/or become indespensible to the business where they work.
Or, they can always form their own business, pay themselves what they believe is a "fair wage" and stop crying about "the man".
