Causation goes both ways. Intelligent, educated, and well-paid Hacker News posters often don't understand the cloud of chaos, crime, poor decision-making, and deflected blame that hovers over the lives of many poor people. Section 8 landlords understand that while such people may comprise a minority of their tenants (or not), it only takes one to ruin a building and the surrounding neighborhood.

On a certain level this is common knowledge, reflected in the real estate markets of all big American cities. Dirt-cheap housing stock can be found in large swaths of Detroit, Chicago, Milwaukee, St. Louis, et cetera. It's cheap because even the most desperate families would rather live anywhere else, around anyone else.

Meanwhile, we refuse to house our homeless but will give $6.5B to Samsung to build a chip plant.

Prioritising homeless doesn't contribute to the society, prioritising plants, factories and businesses contributes.

Prioritising business just concentrates money in the hands of people who already have money while nothing to address the day to day concerns of actual people.

Did you read my comment about a largeish portion of the actual people?

concentrating/diffusing poverty is a different axis of policy vs. housing/not housing the destitute

the unfortunate circumstances surrounding NYCHA properties was due to concentrating poverty, in singapore public housing is economically integrated so as to avoid the same problem
