Editing Labour power (section)

==Wages and labour costs==
Marx regards money-wages and salaries as the ''price'' of labour power (though workers can also be paid "in kind"), normally related to hours worked or output produced. That price may contingently be higher or lower than the value of labour power, depending on market forces of supply and demand, on skill monopolies, legal rules, the ability of negotiate, etc. Normally, unless government action prevents it, high unemployment will lower wages, and [[full employment]] will raise wages, in accordance with the laws of supply and demand. But wages can also be reduced through high price inflation and consumer taxes. Therefore, a distinction must always be drawn between ''nominal gross wages'' and ''real wages'' adjusted for tax and price inflation, and indirect tax imposts must be considered.

The labour-costs of an employer are not the same as the real buying power a worker acquires through working. An employer usually also has to pay taxes & levies to the government in respect of workers hired, which may include social security contributions or superannuation benefits. In addition there are often also administrative costs. So, in the United States for example, out of the ''total'' expenditure on labour by employers, the workers get about 60% as take-home pay, but about 40% consists of taxes, benefits and ancillary costs. Employers may be able to claim back part of the surcharge on labour by means of various tax credits, or because the tax on business income is lowered.

There is typically a constant conflict over the level of wages between employers and employees, since employers seek to limit or reduce wage-costs, while workers seek to increase their wages, or at least maintain them. How the level of wages develops depends on the demand for labour, the level of unemployment, and the ability of workers and employers to organise and take action with regard to pay claims.

Marx regarded wages as the "external form" of the value of labour power. The compensation of workers in capitalist society could take all kinds of different forms, but there was always both a paid and unpaid component of labour performed. The "ideal" form of wages for capitalism, he argued, were ''piece wages'' because in that case the capitalist paid only for labour which directly created those outputs adding value to his capital. It was the most efficient form of [[exploitation of labour]] power.
