How anticapitalists define capitalism.
So when it comes to conversations about economics, there's a tug of war over what "capitalism" means, and the pro-capitalists seem to be struggling to assert their definition because the anti-capitalist definitions are very entrenched.
Which is a bad thing because anti-capitalist definitions of "capitalism" tend to be biased garbage. "Capitalism is when bad things" is a phrase that alludes to this, but I see there's some need for a breakdown.
1; Capitalism amirite?:
A lot of people are casual anticapitalists, and don't really have a definition. They're operating on a socially infectious habit of blaming everything bad on capitalism. Rich getting richer? Capitalism. Small business struggling? Capitalism. The snack you like getting discontinued? Capitalism.
To these people "capitalism" doesn't have a real meaning, it's just a convenient scapegoat and bogeyman for everything they don't like.
2; Capitalism is this list of bad things:
It can be greed and corruption, corporations, a "system defined by exploitation," whatever the specifics, "capitalism" is defined this way is synonymous with evil.
Not much to say about it, it's just blatant with bias.
3; Capitalism is basically everything (but actually just the bad things.)
This one is a bit more convoluted. This is a case where someone starts with a definition of "capitalism" so broad and all-encompassing that it doesn't have any meaning.
From there, "capitalism" can conveniently be blamed for every negative outcome in a system. (While any positive outcomes are ignored, disqualified, or otherwise not credited to capitalism.)
In summary: "Capitalism is when bad things" is an apt summary of how critics of "capitalism" describe it.
For your typical critic of capitalism, "capitalism" isn't a clearly defined system or set of principles that lead to bad outcomes, by their biased definition, it is the bad outcomes. (See also the logic underpinning "not real communism" where a bad outcome isn't communism, "communism" is the utopian outcome they want, so any failures automatically don't count.)
