The presence of one poor person in a society of wealth and plenty is a poor reflection on that society and values. Where, from a position of plenty, they cannot seem bring themselves to help lift someone left behind.
I don't entirely agree with you.
Some people really are in poverty because they make poor, self destructive choices. IMO, any decent society allows for its people to have free will to make poor, even horrible, self destructive choices. An alcoholic CEO who refuses to get help and eventually loses his/her position, family, home, etc. should be free to make such horrible decisions---and to suffer the consequences of those terrible decisions. AND also should be provided the help they need in order to regain their sobriety and hopefully work their way out of poverty if that's their desire. For one example. I think we will always have addicts, thieves and other criminals. I think we need to treat them all as though they can make better choices, conquer their addictions and live a more stable life, including more economically stable life. I do not think that society should enable addicts to continue their self destructive and destructive behavior (It's rare that an addict's addiction only directly harms the addict.)
Some people are in poverty because of positive choices they make to live simply, without much in the way of possessions or income.
What I believe is incumbent upon any decent society is that the legal rights of those who are in poverty are not less than the legal rights of those of more means, including those with extreme wealth. Laws should apply equally to billionaires and the homeless.
I also believe that any decent society should provide for all the best possible health care, access to decent and affordable housing (even if affordable means at no cost to the resident) and food, access to the best possible education, clean air and water, basic safety from crime and protection/help in the case of natural disasters or other events that cause people to tumble from stability into precarious positions.
We've got a long ways to go.
