A failed social system is always the consequence of a lack of social policies, either due to ineptitude or disinterest, inherent to neo-liberalism, when percentages in the stock market are more important than the well-being of the population. This is where poor and homeless people are produced, instead of preventing them from reaching this condition. Having a fixed home is a vital and basic condition for social reintegration, since without an address it is impossible to get a job or to even have a bank account and with this it is also impossible to get a home. A vicious circle that you enter once you are on the street. But there are other possibilities as shown in Finland, how to reduce Homelesness and with an inversion initial, above saving money in social costs.
