By Thomas Gallatin, Patriot Post - ..., the biggest factor in homelessness — and a big one in the very related rising cost of housing — is the Biden/Harris administration’s de facto open border policy. With some 10-20 million illegal aliens having entered the country since Joe Biden and Kamala Harris took office, it comes as little surprise that many of these homeless people are migrants... Take Massachusetts, for example, where roughly half of the more than 7,000 families in homeless shelters are migrants. Seven out of 10 homeless in Chicago are illegal aliens.
