I think capitalism sucks, not because there is not a single place on earth where it is detrimental, but because there are plenty of places where it is. There are obviously the big offenders - the faceless megacorporations in the US and stuff like that. It's not like I'm saying it's impossible to get capitalism to work. I'm just saying that it sucks that it incentivizes stuff like this to happen, even if it doesn't happen everywhere.
and remember... "most establishments" in your area. Some people, live in different areas than you, and the relative price difference is not necessarily the same worldwide.
I don't want to repeat it again, so I hope this explanation is good enough. Just because the video isn't true for you doesn't mean it can't possibly be useful to anyone, if they happen to be in an area where water is more expensive and they're trying to figure out why.
But really, your argument just doesn't make sense to me. It feels sort of like "works on my machine", except it's "water isn't more expensive in my area". Mh.
