Yes- by definition: they take a "vow of poverty."
True, and not a new problem. The wealthy have, through history, looked down upon the "nouveau riche" because they didn't understand how to deal with wealth, and often squandered it. Our celebrity entertainers in the modern world- they have essentially "found" wealth rather than created it, and it's often reflected in their poor understanding of how wealth is created, and sustained, and spread to those who are not yet wealthy.
Refugees may or may not have been poverty stricken before they needed refuge. Many were wealthy or at least working class before circumstance befell them, and they do not lack for motivation, in many cases. However, that motivation can still be stifled and eve extinguished by lack of opportunity.
Yet another class other than those simply ignorant of how to build wealth, are those who CHOOSE to be homeless. Many people simply do not want to work, do not want to follow systemic societal rules, and do not care one way or the other how much stuff they have, or in many cases don't even carefor what other people consider comfort, or necessity. If you don't mind pooping on the ground, and don't care about personal hygiene, a toilet and running water are not "necessary".
Again, 'necessities' aren't always necessary. In Iraq and Afghanistan, we often couldn't get locals to use a toilet. They would rather crap alongside the berm around the camp than use a port-a-john toilet. To them, what we consider basic, necessary hygiene was not only unnecessary, it wasn't even desirable.
If one's customary housing is a bedouin tent, one may well look down on people who live in houses of mud or stone because their lifestyle is static.Is the tent bedouin more impoverished than the person who chose to live in a hut?
Poverty is both a state of mind and relative. To a rich man, someone with less income is living in poverty. To me, a person with high income living way beyond their means is a step from poverty. The primary mechanisms of wealth-building are delayed gratification and future orientation. Sadly lacking in the poor, fairly common amongst the rich. Consider Maszow's hierarchy- is a person wealthy before they achieve self actualization? When they achieve love? Does it take societal esteem? I personally would not trade places with past millionaire John D. Rockefeller, because despite his relative wealth compared to his contemporaries, he lived in a period of appalling scientific and medical ignorance and lack of physical comforts and security that even our modern welfare recipients don't have to endure. I think I would personally put the beginnings of the "wealthy" class at the stage where they have achieved physiological needs and a measure of future security.
Even rich people collaborate to invest in large projects.
