Are capitalism supporters just apathetic?

A couple of minutes ago i was "debating" with a liberal friend of mine and i noticed a bit of a trend. She didn't really give many valid arguments. She said things like "there isn't such thing as a perfect system" and "it is what it is", also being more concerned about her as an individual, stating that she's an "upper middle class" and doesn't want to lose her "high quality steak at weekends".

Is supporting capitalism just not having much critical thinking and having a more individual view? Thank you, by advance
