Thank you for your well put reply, and I agree, your position is not without roots. Though, I'd like to humbly suggest that your points may actually support the notion that runaway modern capitalism does not effectively determine a person's value. I would argue that the fact that a paragon can struggle economically and a grifter can swindle their way to high fortune shows that capitalism does not equitably reward good and punish evil. Therefore, a person should not allow their financial status (the value capitalism has assigned them) to be the measure of their personal value.
On the point of the system's undervaluing of people and their work (which is absolutely true) making it harder to lead a simple life, I'm not sure the two are connected. Being compensated well makes things much much easier, but that doesn't make things simpler. A person can live a very modest life that is simple, tranquil, and full of joy. Someone can also be extremely wealthy and ambitious with a fast paced life full of complexity, stress, and anguish.
I'm very sorry that youre feelings stuck. It's frustrating and it absolutely can feel patronizingly when you're struggling for better and someone tries to placate you with platitudes. But, the gift of simple living is that by appreciating the little things, removing stressful complexly, and slowing down, anyone in any situation can have more peace and happiness in their situation, even if it doesn't get better.
Warmest wishes my friend and be well.
