The common man is the sovereign consumer whose buying or abstention from buying ultimately determines what should be produced and in what quantity and quality.
Ludwig von MisesIf the present American laws concerning the taxation of the profits of corporations, the incomes of individuals, and inheritances had been introduced about 60 years ago, all those new products whose consumption has raised the standard of living of the 'common man' would either not be produced at all or only in small quantities for the benefit of a minority. The Ford enterprises would not exist if Henry Ford's profits had been taxed away as soon as they came into being.
Ludwig von MisesThe [liberals] consider profits as objectionable. The very existence of profits is in their eyes a proof that wage rates could be raised without harm to anybody. They speak of profit without dealing with loss. Profit and loss are the instruments by means of which the consumers keep a tight rein on all business activities. A profitable enterprise tends to expand; an unprofitable one tends to shrink. The elimination of profit renders production rigid and abolishes the consumer's control.
