My view on Prosperity vs. Poverty is that once you give up on finding happiness in material things (and outward appearances) and focus on the things that really matter, then things like prosperity cease to matter. If you're in poverty, then cool... If you happen to be prosperous, then that's cool too, but no one can take away that thing that truly makes you happy if it isn't measured in shallow outward or material standards.
Operate from the soul and not the ego. I wish I could truly do accomplish this. the people I have known whom truly live like this, are much happier, less anxious and generally more "present" in their lives.
My view on prosperity is slightly different. Money doesn't buy happiness, but money does buy security. Security enhances peace of mind, which subsequently enables happiness. Happiness tends to flow outward towards others. Prosperity in and of itself doesn't promote positive behavior, but it does make it a little easier to be more generous. I tend to give more now than when I lived paycheck to paycheck. That said, if you're well to do and still obsess over money, then you're battling your own demons. No amount of wealth will heal a soul in conflict with itself.
I find the thing I'm most possessive of is time. There's a finite supply of it and I can't create more. If I'm giving you my time freely, you're getting something more valuable to me than money and in some way, you've earned it.
