The problem as you correctly put is that people worry, but that does not lead to a solution. There is really no point in worrying - if you cannot change something, why worry about it? If you can change it, why worry? You might have to think deeply about how to change it and act on it, but just worrying is like praying - it gives an semblance of action without actually doing anything.
The hamster, the wheel and the cage are illusions. We choose certain things as more important to us than others. You can always quit and walk out, but a lot of times we prioritize our comfort, an (illusory) stable earnings etc. over freedom.
Worrying clearly has a function, or else we would not have evolved to do so. Worrying motivates action - it is a countervailing force to laziness. Worrying draws conscious and subconscious attention to problems that need solving. It is necessary, like pain. How do you know you can't change something without thinking about it? Why would you think about it if you weren't worried about it?
I charitably interpret all the anti-worrying propaganda as an exhortation to try and maintain worry as a transient state that goes away when you commit to a course, as opposed to an ongoing coping mechanism.

1. Can I do something about it right now? If so, do it, and stop worrying.
2. Can I do something about it later? If so, wait til later, do it, and stop worrying.
3. There is nothing I can do. If so, there's nothing to worry about because I can't do anything about it.
Jesus said, "who of you by worrying can add one moment to their lifespan?" (or in another saying "...add one inch to their stature?")
We are more mobile today than at any point in history, to be honest[0]. Indentures servitude has been abolished to a large degree[1] and slavery has been outlawed[2]. Conscripted military service is gone in America and a lot of European countries[3]. Job mobility and the ability to save money is, while not easier than any point in history on a point by point history basis[4], on a macro scale of history - comparing medieval, renaissance or previous Europe and Russian and Chinese wealth distribution, mobility and freedoms of self - rent/mortgage may be due, but you can still break your agreement, sell your house[5], quit your job and be a homeless ascetic if you want. There are dozens of YouTube channels on VanLife you can watch people doing it... not for me, but you can do it. You can join an abbey[6]. You can leave the system and jump off the wheel, you just have to jump off the wheel and stop getting what the wheel gives you.
[0] at least in western European style cultures... for a large portion of the world, this statement might hold true, but to a much lesser degree, if at all
[1] this can be argued, but this is argumentative on the basis of predatory and college loans
[2] again, this can be argued than prison labor is a form of slave labor in states like California when used to fight wildfires, but I'm not sure how much water those arguments hold
[3] though several have mandatory service requirements
[4] the 60's and 80's, I believe were easier... check my math, I might be wrong, there may have been others
[5] there may be a penalty
[6] though, I think you could have always done this... I'm not sure about this
I'm not sure it's really all that different now than it has ever been. Sure, it's not like people were always and everywhere working for some other entity in what we'd tend to recognize as a "job", but there has always been a struggle. The struggle in the past was to be able to grow enough food to last the winter to stave off starvation.
If the rent is due and there’s no money, what can you do now to fix that? What action can you take, right now, that gets you closer to paying rent? All the worrying in the world does nothing to fix the situation.
Yes have a long-term plan, follow a strategy, even make time in the day/week/quarter to realign and think about that stuff. But when shit hits the fan, only doing something right now gets you closer to a solution.
(Although lately I've been realizing that if we were just cold calculating machines maybe we wouldn't have complex drives and passions, so probably emotions are not just an extraneous 'curse', and are part of why we do what we do.)
Learning to focus is one of the hidden lessons in "Kung Fu Panda." Po's journey allows him to finally reveal to his father his true passion because he learns to focus on his own destiny rather than letting the pressures of the larger society, as represented by his father's expectations, control him.
No, it's not easy. But there's also the early retirement people, who spend little and save aggressively to escape the hamster wheel.
And there is also the mentality of not letting the thing you do to pay the rent or mortgage define you. Put in your 8 hours, but don't let it consume you outside of those hours.
You don't have to spend your whole life in the noodle shop. There are other ways to live.
This seems like a minority these days. Most people are just chasing the house ownership hamster wheel.
I can be moved by this philosophy all the way to tears and crying (and it did happen in the past). However, the even more tragic part is that it doesn't exactly apply in today's world where most people are bound to their jobs. If they don't "worry" about the future and quit and try to do something else that doesn't work out... well... rent / mortgage installment is still due in two weeks.
I really LOVE the philosophy you cited. I just can't see how it's applicable to today's world. The system is specifically made to keep us as hamsters on wheels.
