Pioneer, Mel makes a good point, which I think you may have overlooked.
There are people in dire situations who are at peace and others in the same situation having panic attacks, nervous breakdowns, or lashing out at others.
The more spiritually developed people actually need less--especially in America where our entire economy is based upon consumption. Much of our desire to accumulate things is a consequence of programming by corporations driving us to consume, so that we increase their profits.
The problem is we can never get enough of things we don't need, so we are never really satisfied. This is why, for example, people of modest means, buy more clothing than they can ever wear. Their closets full of clothing with the price tags still on them and they are still not happy and they don't know why.
Don't think of it as first we eat, then we exercise, and then work on spiritual development once everything else is done. Spiritual development should run throughout your entire experience, while you eat, while you exercise, while you fight racism.
