<prompt> Human: If you are among the 20 million Americans saving for retirement through Vanguard, you may be in for an expensive shock.Vanguard is under fire by former Vanguard tax lawyer alleging that the companys low fees are an illegal tax dodge. This could potentially warrant up to 35 billion in tax penalites if the case has merit.EDIT:I know the title is scary, but there is no reason to worry or panic. The case will be tied up in court for quite a while, and if it is ruled against Vanguard, it would only effect rates in the future going forward. If the rates that they charge were to go up by an extreme amount, you can just rollover the money into another investment fund.  <response>: From rfinancialindependence A lot of his cases are being dismissed, and this has been going around for quite a while now him threatening to sue. Based on the first post, its been well over a year that he filed lawsuits
