If America wants to continue enjoy the # 1 position in the world, then the outsourcing of hard-working middle-class and lower-class Americans' technology and service jobs to cheap-labor and no-quality India must stop.
If America wants to continue enjoy the # 1 position in the world, then America must enforce equal/fair/balanced tax system on all of it's citizens. Today middle-class and lower-class hard-working Americans pay 30% of their incomes as taxes, whereas rich and uber-rich Americans pay hardly 14% of their incomes as taxes. Taxes on rich and uber-rich Americans must be increased and taxes on hard-working middle-class and lower-class Americans must be reduced.
If America wants to continue enjoy the # 1 position in the world, then middle-class and lower-class Americans must be paid fairly and they must be given deserving benefits. Today any business's management gets multimillion dollar bonuse at the same time rank-and-file employees are denied well-deserved salary hikes and benefits.
