Editing General formula for capital

Normal [[commodity]] circulation C-M-C (commodity-[[money]]-commodity) does not allow for aggregate growth like that which [[capitalism]] is notorious for. The farmer starts out with some number of beets, sells them for money, uses that money to buy a pewter wizard figurine, then goes home no richer than before. Money becomes capital when it manages to grow. The ''General Formula for Capital'' is M-C-M’, where M’ or 'money prime' refers to an amount of money M’ > M. 

How is this possible, assuming exchange of equivalents? (Remember, Marx is.)
The commodity wage workers sell to capitalists is our [[Labor-power|labor power]], our ability to work, or simply our time, fractional parts of our lives. Labor power, like every commodity, has a value (in this case the wage the worker receives, which corresponds to how many hours of [[Abstract and concrete labor|abstract labor]], on average, are required to reproduce the worker’s ability to work at their expected standard of living) and a [[Use value|use-value]] (in this case real labor performed, e.g. sewing or typing). This is a very special use-value because labor can create [[value]]. As long as capitalists buy and use labor power, it’s possible for them to sell the products of labor and end up with more value than they started with, '''M’ > M''' relationship.

The capitalist’s starting capital (M) can be split into two types of expenditure, [[constant capital]] (c) and [[variable capital]] (v), where M = c + v  and similarly, M’
Furthermore,
'''M’ - M = [[surplus value]](s)''',
so 
'''M’ = c + v + s'''
and here in 
'''v + s'''
is the value produced by the workers who were paid v for their labor power.
