Exactly. If a small group of people are given UBI, then they just have more money, and stores want to profit from everyone, including the people who aren't getting more money. But if everyone gets UBI, then the stores are sure that their customers can afford higher prices, and our current government has shown that it doesn't care if prices are arbitrarily inflated. I'd love UBI, but it can't function alone without accompanying laws to prevent price hiking.
