The Universal Declaration of Human Rights states that every person has the right to a home, yet this human right is being violated in countries who clearly have the means to adress the problem. Why is it so?
The Universal Declaration of Human Rights, was written after World War 2 by the United Nations General Assembly (10 December 1948), this document was supposed to protect the world from future atrocities like those committed by Hitler during the second world war.
Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.

But at night the streets are being filled with people in sleeping bags, in rich countries, countries that could easily address this problem, this is something that really makes me disappointed with humanity...
Is this something you even care about?
I would really like to see a change, but what can we do?
The U.N actually did a report on this clear violation of human rights in 2015, here is a quote from this report:
Those who are homeless are constructed as a social group. Worldwide, their identity is created and then reinforced by people who have more money, more power or more influence. It is a vicious circle. Laws, policies, business practices and media stories depict and treat homeless people as morally inferior, undeserving of assistance and authors of their own misfortune, and blame them for the social problems they come to represent. Once stigmatized, their needs are further neglected and inequality and discrimination further entrenched.
This report also mention different projects and measures that countries are taking to prevent homelessness, but not much has happened in reality as far as I have seen anyway, you can read it here: https://documents-dds-ny.un.org/doc/UNDOC/GEN/G15/294/52/PDF/G1529452.pdf
I know some people are paranoid about the U.N, maybe after watching too many Alex Jones videos? But I think they are pretty cool, I don't think they intend to put all the homeless people in camps or something like that...
But until someone else changes the world for you, what can you do?
One possible solution: "Tiny House Movement"
Source: Wikipedia, Tiny House Movement.
One grassroots movement that take this matter into their own hands, is the "Tiny House Movement," by choosing to live in a tiny house one can put the power back in the hands of oneself, there is no need to become a "debt-slave" for the rest of once life either, because building a tiny house can be done with a small or fairly low initial investment.
Supporting or getting involved in the "Tiny House Movement" can be a way to fight homelessness at a grassroots level and you don't even have to try and prosecute your own country in the International Court of Justice!!!
If you want to read more about the Tiny House Movement you can check out this 2018 article following up on people in San Fransisco who have been testing it out for a while, San Fransisco is one of the most progressive cities in the world, but San Fransisco has "crazy" rents, read more here: www.sfgate.com/realestate/article/Bay-Area-tiny-home-micro...
