Thanks for posting that. Some people have wasted some breath on criticizing Dave, but I wonder if they even listened to what he was saying.
Hey you are right, after listening to this, I've realized that not only have my criticisms of him been valid, but I have been too kind to him. In this video, he advocates for someone to aggressively pay down a debt that has 1% interest, instead of investing money in an investment that would reliably make 10 or 11%. His excuse for that is the idea that investments carry risk, and the 10 or 11% rate of return does not account for risk.
He then mentions Beta as a justification, without adequately defining what it means or going through the math to explain his reasoning. He has his own show, he could take the time to explain all of this. Beta is a measure of volatility compared to the market. It's useful as a measure of risk for short term investments, but the guy calling specifically mentioned the idea of investing in a Roth IRA, which is a long term investment for retirement. Beta is not very useful for determining risk of long term investment, and it's more important to look at proven performance of investment products over long periods of time. We can pretty reliably say that high growth mutual or index funds can reliably average 10 to 15% per year of growth, tracking that fund over 10 or more years of time.
Of course, even if we decide to use beta to determine risk, the idea that the beta of a mutual fund that over time yields an average of 10-11% would make it less sensible to invest in it instead of aggressively paying a loan with a 1% interest rate really is more dependent on facts that Ramsey does not even ask about. Job stability, current savings, whether the caller is likely to be able to continue to save or dip into those savings, etc. There may be some instances where it does make sense to pay down that 1% loan aggressively, but in most situations, the investment option leads to more wealth over time.
Honestly, even his anecdotes sound very strange. There is no way in hell that Ramsey has not talked to millionaires who developed wealth by using cheap debt. it's incredibly common. Basically all mortgages depend on the concept of using cheap debt to develop long term wealth, and home mortgages are the primary vehicle that the vast majority of people in the US use to grow their wealth. He is either lying, or he does not understand pretty basic economic concepts.
