Physically, sure.
Because the OP seems to be only upset at some unknown tipping point. The folks walking by are fine except for those who have expensive cars who should be rendering medical aid.
Also, random “assistance” from passersby could make the victim’s situation worse despite good intentions.
I agree with OP . I work for someone on the Forbes list of billionaire. She gave away 500k to a certain uneducated republican governor. Just imagine what good could have come from that amount of money in this community. It’s stunning if you think about it.
OK, so you don’t want laws against the accumulation of wealth; you just want the accumulation of wealth to be socially unacceptable. Why do you favor social proscriptions, but not legal ones? If you are opposed to the accumulation of wealth on an individual basis, why do you not want to utilize social and legal tools to achieve your goal?
These days, most wealthy people are wealthy because they did something that was very valuable for other people. Should we all approach Michael Jordan and tell hm, “look, we know you entertained millions of people with your athletic prowess, but we think it’s wrong for you to drive a $100,000 car and just golf for fun all the time.”?
How would you feel about a person who has the ability to earn money very quickly (in terms of dollars per hour), but then chooses to work only an hour or two a day, living a life of leisure on a modest income, instead of working full time and earning boatloads of cash to pay the rent for a neighborhood full of low-income folks?
[quote=Robert163)It is my position that a society where people worked harder to help each other than on getting a better car is a better world for people to live in. [/quote]
The problem is that you are not arguing for a society in which people work hard to help each other; you’re arguing for a society in which high earners work hard to help everyone else.
Well, to the guy lying on the ground writhing in the pain of a heart attack, walking might seem to be a excessive luxury. If the bystanders had any morals at all, they would start snarfing down fried Twinkies and Big Macs so they could be down there with them.
Now there’s a philosophy I can get behind! 
I also noticed our snivelly little OP seems to have vanished. Because “Thinking is hard”, no doubt.
Detroit?
Tragedy of the Commons!
However, if the OP were about the wealth gap causing social, political & economic issues—that would have been a lot closer to the mark.
