You don't really think WalMart is going to stop discounting do you?
Unrelated, but yeah, when they have a 100% market share on retail super stores.
Back on topic. You don't need to have a degree from Harvard to reason this out: Obviously someone had to fight for this decision. Someone felt it would benefit their interests if this restriction was removed.
That being said, it probably wasn't a consumer advocacy group that fought for this overturn (sarcasm). Go ahead and mark the consumer down and out.
I doubt it was a specific retailer that was fighting for this either, right (sarcasm)? So we can count the retailers down and out.
What does this leave? Manufacturers win. Why did they fight for a regulation held in place for half a century? Look at the composition of the supreme court... probably the worst for this country since the regulation was passed (however unrelated). The effects of the overturning will vary and no one can guess just how things will turn out, but you can feel safe to bet on the Manufacturers getting the longer straw.
