For those trying to shop ethically in 2025 - Aldi and trader Joe's are owned by the same company, both union bust and both companies in the US (they are European owned) use prison labor. In America that means slave labor. Whole foods is owned by Amazon and busts unions the same way they do for the where houses. Kroger has a union but it's a union that exists to protect the company, and not the workers and they fire you if you don't want to join the union. Marsh doesn't really exist anymore.
