WOTC - How should salaries be determined?

I asked this question in the Wisdom of the Crowd - How should salaries be determined?

Here are the responses:
44% - The salary should be a living wage, adequate to meet the cost of living.
25% - The salary should be negotiated between the employer and individual employee.
17% - The salary should meet a guideline for each occupation provided by the government.
14% - The salary should be negotiated through collective bargaining between the employer and the trade union.
