Really? Any more reckless than allowing 401k account holders to trade futures and options contracts in the US?
Uh, where can Joe Blow employee trade futures/options in his company's 401(k)? If that's happening, I'm sure not aware of it.
If you're talking about self-directed IRAs/401(k)s, that's a whole different category. The average clueless investor knows nothing about them. They're used by more sophisticated types for real estate, managed futures, etc.
