Not specific to this video - but some of the longer term assumptions most people take while doing financial planning are unlikely to happen. E.g., how can we assume equity markets will uniformly return 12%. What if equity markets are going through a bad phase when one is retiring? The return can be much lower + even the longer term upside looks unlikely. Also it’s wrong to assume mid caps will give returns at such a high rate. The second flaw is the income growth & savings assumption. Career tracks are likely to be broken from here on. Staying consistently employed or earning regularly through business or freelancing & earning consistently is unlikely.
