I didn't mention any company other than Costco. They have built their trust with me over a few decades of consistent service and objectively cultivating better working environments than other similar establishments.

I also know all of their net income comes from membership fees, which means the margins for their products is likely going into essentials (I haven't heard of their organization indulging on lavish pay and parties and whatnot).

Of course, as a buyer, it is in my interest to have multiple vendors around to keep them competing. Unfortunately, I don't have the resources to go to other wholesalers also. However, technology does tend to reward the most efficient with all of the gains, so we seem to be inevitably going towards a future with fewer competitors and at most 2 or 3 businesses dominating each field. I don't know how to solve that problem, since as a buyer, I greatly benefit from the conveniences the efficiencies of scale afford me, but I know in the long term, the tables can turn and the seller can gain power over the buyer.
