There’s a perpetual pundit debate over the best way to provide for retirement: defined benefit plans (pensions), defined contribution plans (401(k)s, IRAs and the like) or pay-as-you-go social insurance schemes (Social Security). Most retirement experts I’ve talked to prefer a mix of these, a “three-legged stool.” But as I’ve written before, this is a bit like arguing whether the Titanic would have survived the iceberg if only its hull had been painted green. All three types of retirement savings have different costs and benefits. But these costs and benefits are not the primary reason that people in Western countries have to worry about an impoverished old age.
The funny thing is that, for all the people arguing that some dire problem in one of these three retirement systems urgently requires that we switch to another kind at once, the major problem with all three is exactly the same. It’s even a problem that’s easy to state and easy to fix -- no need for extensive blue-ribbon commissions or elaborate white papers. Here’s the solution: Pick whichever system you prefer; it really doesn’t matter. Now slap a 10 to 15 percent surcharge on a worker's wage income, and divert that money into the system for the worker’s future use. Problem basically solved, because in all three cases, the only flaw that actually matters is that they’re badly underfunded.
