Wages
Hass you may have heard, the USA actually has quite a large number of poor and homeless people roaming the streets in certain areas. A lot of the country can be unsafe to walk alone at night. Of course, there are good areas as well, we do not mean to scare you.
But a big factor as to why there are so many people out on the streets without a home is that the minimum wage is not enough to live off of. How are you supposed to pay rent and cover the other costs of living when you simply do not make enough money to do so?
