Most Americans don’t look to their 401(k) plans for excitement or experimentation, instead relying on the promise that steady saving and sober planning will guarantee security in their golden years. But the Trump administration wants to transform the well-worn patterns of retirement investing.

To do so, it is moving to weaken the main protection workers have over their retirement money. The man in charge of the regulatory rollback is an industry insider whose former clients are among the large companies likely to benefit from his plan.

Since taking office last year, President Donald Trump has loudly called for plans to include less-regulated — and often risky — investments like private equity and cryptocurrency. To achieve that goal, the administration is softening one of the strongest legal protections American workers have: the right to hold an employer accountable when retirement savings are mishandled. The change is designed to give employers cover if their workers’ 401(k)s are deflated by expensive, opaque or unproven investments.
