If this poor sap is found guilty, he's going to jail, likely for a few years.
However, being poor, and not understanding how things work, yet still having the ability to fxxk things up; that's what happened here. This guy might have had a bad job that was engineered away, or maybe his job was offshored to someplace with lower taxes.
Once you leave urban areas in southern states, the ONLY jobs available are not possible to be offshored. Some jobs, such as government work like teaching, law enforcement, sanitation, etc., need credentials. Medical, legal, and other professionals cannot afford to practice where there's no money. This leaves low-wage agriculture and low-wage service jobs. If you have no money and no hope, terror seems like the way to go.
This bomber guy is not alone. The next one might have his ---- together.
