<prompt> Human: As someone who entered the working world in 2012, I did my due diligence and read everything I could on finance, from this sub, to the early retirement blogs, to a Random Walk, and all the classics. The consensus was overwhelmingly in favor of passive investing, so thats what I did, exclusively. It was always billed as something of a secret, how most people didnt know about it, but it was really the most efficient way to grow your money. Now, at least one reputable person seems to think this type of investing is hitting the point of making a bubble. What do you think?  <response>: This is coming from a site that wants you to subscribe for stock-picking tips. Be wary.
