When you purchase something from a company you are buying the commodity not the labor used in its making. A commodity has many costs wrapped into it, including labor. The profit a commodity brings to a company doesn't have a 1-1 relationship with the wage of a laborer, so a consumer buying a coffee isn't buying the labor of someone else, they are buying a product. "Buying human labor" means you are an employer paying a wage or rate. Generally employers are people or entities that have accumulated wealth through profit. It's fair to say these people skew towards wealthy, hardly a silly statement at all.
