Agreed: per the article: "There's evidence that lower-paid workers aren't widely participating in Amazon's 401(k) plan—and that creates a problem for high earners at the online retailer. For a plan to maintain its tax status, it can't disproportionately benefit what the IRS calls "highly compensated employees." A lack of participation by the rank and file means higher-paid employees can't max out their contributions to the IRS limit and may even get some of their planned savings back. Every year since at least 2011, Amazon has had to repay amounts "withheld and contributed to the Plan that exceeded the amounts allowed under the Code," according to the company's 2013 regulatory filing for its 401(k) plan. This year, it repaid more than $5 million in excess contributions made in 2014. For employees, that can mean paying more income tax and filing an amended tax return."
