I am interested in what is driving this? Need to understand that to even begin to fix it. Is it drugs fueling mental illness issues? satanic issues? Why more in these days than before?
Lack of the Bible.
Lack of the Church being salt and light and engaging in the Great Commission, and instead becoming PC. As Jerry Falwell said, you can be JC or PC, but not both.
Lack of the Church ensuring The Gospel goes in with social ministry
Lack of Pastors exercising Pastoral leadership inside AND outside the Church and failing to stand up for what is right instead of caving in to PC.
Social zeitgeist driving the Church, instead of the Church leading society. Good being called bad and bad being called good.
Lack of Church discipline with real consequences instead of PC
Lack of parents bringing their children up IAW the Bible and in the church.
Drug epidemic, fueled by BigPHARMA opioids/opiates, then abusers migrating to heroin and fentanyl when prescriptions stopped instead of weaning.
Lack of schools and parents teaching self-reliance and strong work ethics (homework, chores, etc.).
Able-bodied sitting on butts and collecting tax money via programs, etc. and draining resources, instead of working, or at least volunteering, and building/contributing resources for the collective good.
Social services systems structured to trap people in poverty (notably Section 8), encourage out-of-wedlock births (increasing benefits for additional children), and fail to help mentally ill, who often don't understand they're sick and need help.
Corrupt criminal justice system that warehouses, brutalizes, and fails to rehabilitate and set people up for success upon release.
Greedy/corrupt developers and government officials causing affordable, single-family housing, to be torn out and replaced with multiple family housing, from which only the developers, apartment owners, and property management companies make a profit, and the government, which collects more taxes than it did from single family homeowners.
Increasing rental and decreasing homeownership rates. Blocking upward mobility by removing starter and other modestly priced houses. This also has the effect of making seniors and elderly very housing-insecure, just from inflation. Rent is almost always a lot more expensive than a mortgage, and there's no return (equity) on rent. Here, there's added pressure on housing stock because of the huge number of refugees and immigrants, for whom the refugee and immigration services purchase and rent available housing. Owners often prefer institutional rent-payers because there are deep pockets available for higher rents and almost-always enforceable recourse if tenants damage the property.
Higher rental rates and lower ownership rates destabilize neighborhoods, reduce cohesion, increase crime, and over time reduce property values from only maintaining instead of improving property. Lack of yards reduces trees and other plants for aesthetics, atmospheric scrubbing, water filtration, shade, prevention of erosion, etc. Lack of yards reduces the number of people who are able to grow at least part of their own food, which increases dependence on, and demand-side pressure on groceries, which increases prices.
Rent opens people's residences to government intrusion via "code inspection."
Property managers and owners of multifamily housing can limit/eliminate gun ownership by making their properties gun-free zones/properties. Ditto dogs and cats.
Renting instead of owning necessitates people having roommates or working multiple jobs, both of which reduce quality of life and increase stress. Increased stress contributes to more substance abuse, mental illness, and violence, all of which eventually cause eviction and provide excuses for government legislation and control.
As the number of homeless, mentally ill, and substance abusers increases, the availability and quality of services decreases due to supply and demand. Ditto utilities and infrastructure.
There's a lot more . . . I could write a book . . .
Persecution of the Church, and thus strengthening and emboldening it to do what it should be, would go a long way to fixing today's spiritual apostasy and apathy, moral bankruptcy, and social, economic, etc. problems. Same pattern as been for the last 2000 years.
God warned against apartment-style living:
8 Woe unto them that join house to house, that lay field to field, till there be no place, that they may be placed alone in the midst of the earth!
Isaiah 5:8, KJV

If homeless had one or two large sites to set up in, needed services and infrastructure could be provided, and those, who are actually trying to get off the street, would have access to help to do so. Those not trying would also have access to help to minimize harm to themselves and others. When this type of thing is done, and the homeless in the new encampments are given absolute preference in hiring for the jobs and volunteer positions that are necessarily created, including the pre-establishment remediation, planning, and organization jobs, good things tend to happen faster, and bad things tend to diminish. Self-help and self-reliance instead of outsiders "doing unto" provide a sense of dignity and worth that goes a long way. Add church involvement and stir
