If money alone were all that mattered, you would think a country like the US wouldn't have thousands of homeless, etc.
>According to a 2015 assessment by the U.S. Department of Housing and Urban Development, 564,708 people were homeless on a given night in the United States. At a minimum, 140,000 or 25 percent of these people were seriously mentally ill, and 250,000 or 45 percent had any mental illness.[1]
The homeless problem is a mental health problem. Sure, people can fall into hardship and get e.g. their houses foreclosed on and go bankrupt - but those same people generally are back on their feet a year or two later. Basically everyone who does not suffer from severe mental illness has the capability to raise enough capital on a monthly basis to put a roof over their heads. Now, they may have to work hard, and perhaps unreasonably hard in a sadly large amount of cases, but they can still do it and still do do it given that 99% of the country is not homeless.

There are many factors that contribute to homelessness. Physical ailments can help lead to homelessness, but so can the high cost of housing:
Research by Zillow Group Inc. last year found that a 5 percent increase in rents in L.A. translates into about 2,000 more homeless people, among the highest correlations in the U.S. The median rent for a one-bedroom in the city was $2,371 in September, up 43 percent from 2010. Similarly, consultant McKinsey & Co. recently concluded that the runup in housing costs was 96 percent correlated with Seattle’s soaring homeless population. Even skeptics have come around to accepting the relationship. “I argued for a long time that the homelessness issue wasn’t due to rents,” says Joel Singer, chief executive officer of the California Association of Realtors. “I can’t argue that anymore.”
