If you receive Social Security prepare to sue the Government if they refuse to pay. There is a specific tax designed to pay for this system and the Federal Government has no authority to divert funds each month from said taxes until all entitlements are paid. Obama has threatened to cut payments. If you are receiving Veteran payments either from the Department of Veterans Affairs or Retirement benefits and the Government does not pay you also can sue under the 14th Amendment. That Amendment makes it clear the Government may not default on payments to veterans.
