This is frustrating. I am 100% not choosing to miss the point. 100% not. Can you please explain the key point that you think I am missing in a few sentences?
I'm personally of the opinion that when one comes across a situation which, in their view, reflects a fundamental failure in the way our society works, they should raise it and talk about it rather than choose to "switch off" and ignore under the pretext that "we live in a capitalist society and that's not about to change so just accept it and don't complain." In my view, the situation that we are describing here does reflect a deep failure. The fact that people like Jess are able to sit in their multi-million pound home week after week, month after month, and put in zero work, while others --literally in the same city-- are killing themselves at work and still struggling to make ends meet...IS NOT okay and should not be accepted as a fatality. Economic inequality is a serious issue and it is rising, including in London where Jess lives. It's become increasingly obvious now given the pandemic/recession we're currently going through. The fact that people make money (a disgusting amount of it) off of plastering this obscene lifestyle online for people to watch is frankly not a trivial thing and I believe we should all ask ourselves what it means, what it reflects, the consequences it could have, etc. It is harmful whether you personally feel the effect of it or not. Just because a 'job' exists doesn't make it morally right and doesn't mean we shouldn't question or even criticize the value it adds to society. Just like many people criticize finance jobs for other reasons (for example).
You ask, "Why don’t people choose to compare themselves to those who are worse off?" -- to me the answer is simple. If we were to ignore people who are better off and instead systematically compare ourselves to people who are 'worse off,' that would lead us to accept less-than-ideal conditions and never strive for the improvement of our own conditions. I personally believe in leveling upwards rather than leveling downwards. Isn't the ultimate goal that we improve our societies overtime, that everyone's living conditions improve? If you just keep telling yourself "yeah my situation is shitty but people in other countries have it even worse, so I'm not going to complain about any of the things I'm going through" then how is that sort of mentality going to help improve the situation of generations after you who will be going through similar issues? That's a very narrow way to look at things and actually doesn't help anything or anyone long term. Saying "that's just life" doesn't help anybody. Well, yeah, it helps the people who are already in extremely privileged positions, people like Jess!
