Starting that article out by citing Trump really put a spin on it. I don't think that was a necessary preamble to illustrate the problem and I think it rather biased.
To me, Trump and his sycophants are always scanning for useful scapegoats du jour to bolster their authoritarian agenda and dictatorial movement, plain and simple. The Federal government is not doing much to mitigate the problem, (which now centers on low wages vs. very high rents) and HUD, (which would be the agency to address the issues and offer assistance) is virtually brain dead thanks to the seemingly lobotomized Trump minion, Ben Carson.
Unless there is a plan to attack the causes of homelessness as if not doing so is a problem that affects the commons and therefore is a priority for many important reasons, then an article like this comes across as trumpistic, to say the least.
In other words the takeaway for people who read the article could be: homeless = health hazard. I don't appreciate that and it detracts from the reality of the situation. The people being stigmatized are already having a hard enough time surviving as it is. You would have to experience it to understand just how stressful and overwhelming it can be and your imagination won't live up to the experience, I assure you.
If the health hazards are an important issue, then what would be the problem with providing more bathroom facilities with proper management as one, temporary solution as another comment mentioned? We can leave behind entire military bases as if it is nothing, but we can't provide sanitation for people in dire straights? Poppycock! Something is certainly wrong with that and Trump's lack of concern or aid is merely self-serving for his Fascist agenda, once again.
