Marginal costs exist because:
households and businesses make rational decisions.
most decisions do not involve sacrifices or tradeoffs.
the decision to produce more of some product means the sacrifice of other products.
marginal costs don't do what marginal costs do for marginal costs but because marginal costs are marginal costs!
