Well Kroger is unionized and Aldi is owned by Germans, Food Lion is Dutch, Albertsons is owned by Cerberus, so unless you live in the SE and can go to Publix, there’s not a lot of good alternatives.
I live in central NY State. The only store you mentioned that is here is Aldi's, and I don't go there. The grocery stores we have are Tops (aka P&C), and Price Chopper (Market 32). Then of course there is a Walmart, and within a half-hour drive is Hannaford, and B.J.'s Wholesale Club. About 45 minutes away is Wegman's.
