The fact that you’re enriching the owners by shopping there does not imply that enriching rich people will lead to more Aldis being created.

“Trickle down” isn’t just “rich people found companies” or “rich people buy gadgets when they’re still new and expensive.” It’s specifically about making ordinary people financially better off in a significant way by making rich people richer. It’s not about technology at all, and it’s not merely about rich people doing some things that benefit the rest of us. It’s a causal claim about rich people doing more things to benefit us, and it being a positive tradeoff, by making them richer.
