For comparison, let's start with Costco, a unionized company:

Yeah, Costco's employees are paid by Member dues as 70% of the company's operating income comes from them.

Unlike Wal-Mart, Costco uses a paid-membership business model. Customers need to become Costco members in order to purchase merchandise at discounted price, paying at least $55 per year for the membership. This allows Costco to collect most of its profits 12 months in advance. Roughly 70% of the company's operating income is generated in this way.
