That's not how it works, unfortunately. As someone who was saved from living on the streets by a convicted murderer just out of jail because my family was too poor to afford bills, among other degrading things, there is no "at peace and unconcerned" in poverty. You're imagining a romantic poverty from books and movies, a poverty that doesn't destroy your weight and immune system due to stress, doesn't keep you away from doctors you can't afford and can't take time off of work (if you have it) to visit, doesn't tear down the dignity of choice in how you live your life, doesn't leave you hungry every night of the week, doesn't leave you in situations regularly where you have to fear for your safety but have no choice if you want to survive.
There is no peace in poverty. Poverty is difficult, painful, stressful, and a situation I wouldn't wish on my enemies. I don't have to imagine what it's like to live in poverty, of feeling humbled because I have no choice on what to eat; it's whatever the food bank had that week again. It's easy to romanticize poverty if you've never lived through it; I went to a private school on a scholarship and there were plenty of people there that did it, as well as people in my university who will spend an afternoon a week volunteering and think that they know what poverty is and that it's noble and beautiful and on and on ugh.
