There's never been a more important time to learn the basics of personal finance. It used to be that government and employers could be counted on to provide for our retirement. No longer.

Resistance is futile
Defined-benefit plans are going the way of the dodo, and so, too, could Social Security.

Indeed, as Robert Pozen wrote in The Wall Street Journal this week, "Congress is expected to pass a pension bill that will effectively put the nail in the coffin of defined-benefit plans for corporate America. ... No public company in the U.S. will create a new defined-benefit plan, and the existing ones will be gradually phased out, frozen or converted into cash balance plans."

Trust no one
Then there are the employers that go bankrupt. When this happens, pension liabilities are transferred to the Pension Benefit Guaranty Corp. (PBGC), an arm of the federal government. But there are some shortfalls to this model. First, the PBGC caps payouts at approximately $45,000 a year. Second, there are no health-care benefits.

What's worse, the PBGC already has a $313 billion funding shortfall.

But it's not the only one. Many companies have woefully underfunded pension plans. According to Standard & Poor's data, S&P 500 companies face $140 billion of unfunded liabilities. Some individual companies -- like Comerica (NYSE:CMA), PerkinElmer (NYSE:PKI), and Principal Financial (NYSE:PFG) -- can cover their liabilities. Others, such as AT&T (NYSE:T) and Goodyear Tire & Rubber (NYSE:GT), will need billions to meet all of their commitments.

If that isn't scary enough, Hewlett-Packard (NYSE:HPQ), Verizon, and Sprint Nextel (NYSE:S) have also taken steps to end their pension plans.

The 401(k) solution
Pension obligations have the potential to destroy businesses when times get tough. That's why you see newer companies such as Southwest and JetBlue creating defined-contribution plans (such as 401(k)s) for employees and why Pozen asserts that no new defined-benefit plans will ever be created.

In these plans, the only guarantee is the amount of money that goes in -- not the amount of benefits paid out. This eases the burden on employers, but it increases the burden on employees to make sure the savings are put to good use.

Soon all Americans will be managing their own IRAs, 401(k)s, and maybe even health savings accounts (HSAs). When that happens, it will be up to you (yes, you!) to know some finance.

Know thyself
But ask yourself: Is there anyone you would rather trust your retirement to than you? As comforting as it is to think that there is an omniscient and beneficent god of retirement out there, neither the government nor your employer is capable of being that deity.

Neither cares about you or your future in anything more than an abstract way. Neither knows the details of your life, health needs, or retirement timeline. That's why managing your own future can make your future better.

When you're in charge of your own money, you pick where and how you want to invest. Risk-averse? Short timeline? Consider a bond fund such as Managers Fremont or a low-cost index such as Vanguard Total Stock Market. If you have a longer timeline, you can learn to pick individual equities and amass a nice nest egg as you try to beat the market year after year after year.
