I once did a piece called “The Case Against 401(k) Plans” that went viral.  I wrote it 6 years ago and my main issues (at the time) were that (1) 401(k) plans locked you into only a few investment options (2) a 401(k) plan converted capital gains income into ordinary income and (3) a 401(k) plan assumed you would have less money in the future.

I now recommend the right kind of 401(k) plan, a Solo 401(k) and/or a Solo Roth 401(k) plan to many business owners.  I like this plan because (1) you can completely self-direct it (2) you can invest in real estate and passive business activities and especially make use of some great strategies that do NOT convert the character of the income and (3) you can put up to $51,000 per year per person away in the plan.  

Ironically, though, I often run into someone who read the article back when it was viral and everywhere, who then uses my points to quote, not realizing I was the author.  It is strange to argue against yourself, albeit in a time warp.
