Tens of millions of Americans and their employers pour money into pension plans each month, counting on those funds to grow and to be there when needed at retirement.

But a time bomb awaits. The bulk of U.S. pension funds are dangerously underfunded, and the assets are often invested in securities that have bleak prospects for providing income that keeps up with a general decline in purchasing power.

A pension plan requires an employer to make contributions into a pool of funds set aside for a worker's future benefit. In 1875, when the American Express Company established the first private pension plan in the United States, the face of retirement was fundamentally changed. Before that time, private-sector pension plans did not exist, as most employers were small "mom-and-pop" businesses.

The innovation at American Express caught on. By 1929, 397 private sector pension funds were in operation throughout the United States and Canada. As of 2011, according to the Bureau of Labor Statistics, 18% of private sector workers are covered by pension plans. At the end of 2015, the value of U.S. pension funds was $21.7 trillion.

Millions of Americans will rely on pensions once they've reached the age of retirement. Pension fund managers have a fiduciary duty to safeguard funds against foreseeable risk. With the practices of today's Federal Reserve, there is no risk more foreseeable than inflation, but these fiduciaries are not fulfilling their duty to protect against this significant risk by investing in assets which are specifically suited to defend against the perpetual loss of the dollar's purchasing power.

Chief among these assets are physical gold and silver, the most reliable inflation hedges from time immemorial.

Nothing Is Certain Except Death, Taxes, and Dollar Devaluation

In today's uncertain times, few things are as certain as the devaluation of the dollar. Having lost more than 95% of its value since the creation of the Federal Reserve in 1913, America's unbacked fiat currency has a 100-year track record of declining value year after year. There is no reason to expect this trend to reverse, and the possibility of a total collapse of the dollar at some point cannot be ruled out. This is important because of the dollar's inverse relationship to the price of gold.
