It's more like "I can't afford it, and my rent has been going up faster than my wages because the people who can afford it are an increasing proportion of the local population and I'm angry that the government are doing nothing to help me so therefore I'll take out my frustration on this ridiculous example of free market economics because I'm too stupid to think of another way and using violence to ruin someone else's business that they've put all their own hard work and money in to seems fair to me even though they've done nothing to me and are only trying to make a living".
Of course not all of those involved are those directly affected, but that's something else entirely.
