Sympathize with the homeless?

I volunteered for 30 years at a homeless shelter, whenever I could. In the beginning I mostly encountered people who were involved with drugs, or mental illnesses—or both. In my state, there were public mental hospitals which became privatized—with the result that patients whose families couldn’t pay for their treatment and weren’t assessed as “dangerous” were either transitioned to halfway houses or just released. It’s been in the last 10 years that I started seeing working people in the shelters, people priced out of the housing market, families. Usually it’s temporary, but lately there has been an increase in elderly people who have lost apartments after living someplace for decades, then having the building bought by someone who jacks up the rent.
As an older person, I fear that happening some day when I’m at my most vulnerable.
