> Unemployment rate is very low in the US

Caveat: unemployment statistics don't count people who aren't seeking work. Which chronically homeless and/or drug addicted people usually do not.

> The unemployment rate measures the share of workers in the labor force who do not currently have a job but are actively looking for work. People who have not looked for work in the past four weeks are not included in this measure.

Basically what unemployment rate tells us is that USA has enough jobs for people who want to work. It says nothing about people who have given up looking.
