They are 20% of American population. They are neither middle class nor poor. They are Asset Limited, Income Constrained and Employed.
While rich get richer, poor get poorer, the middle class stays stable, ALICE is sinking down.
They are most discontent with any Government for they cannot cope with all those taxes considered so low: state income taxes, regional income taxes, city income taxes, sales taxes, property taxes, excess taxes (phone, cable, internet, luxury, etc), gas taxes, room taxes, medicare/medicaid taxes, SS taxes, permits and fines. No wonder that those pps aremost politically active as consequence. If U.S.A. would ever face the hell of revolution it would be committed with ALICE's hands.
Still most danger is in cooperation of ALICE and radical islamists. ALICE class has nothing to lose and everything to gain. Meanwhile they are rather aggressive and glad to undermine existing system slow and sure sinking them down.
This alliance is a real menace for America. Just imagine an army of "common Americans" turned into walking bombs. You would never tell such terrorist from your good neighbor until he attacks with "Allah Akbar" yells.
Are you scared? I am.
