"Company stores have had a reputation as monopolistic institutions, funnelling workers' incomes back to the owners of the company. Company stores often faced little or no competition and prices were therefore not competitive. Allowing purchases on credit enforced a kind of debt slavery, obligating employees to remain with the company until the debt was cleared."
