America's pension time bomb

This event has an hint from the NY city transit strike. What caused it? The answer was the Pension." The transit authority is watching its pension costs rocket as longer-living retirees increase in number." union members are dumping or cutting their pensions .
Private emplyees also require their pensions. as mentioned in the article, "The pension wars will inevitably include Congress, which is working out a way to increase funding for the federal Pension Benefit Guaranty Corp., now deeply in the red as huge companies like UAL, parent of United Air Lines, dump their pension plans on it. Since the PBGC is an insurer, the logical move is to raise the premiums companies pay, especially for the riskiest plans."
What is the result from reducing the pension? That's the economic decision a country must make. It could cause different results by different rate of pension. This is also a kind of "trade off" to balance the social security and the pension expenses. The NY city transit strike shows the
unbalance between the pension paid to the transit workers and the security and efficiency of the country.
