I think there is a word for this author, and the word is insufferable. He seems to be afflicted with what I have come to think of as old(er) white man syndrome. It's something I see predominantly in this demographic (both online and in real life): older men who make judgements and recommendations based on the very narrow lens of their own life.
That's why J.L. Collins thinks college students who have loans are feasting on sushi, and that those who make $25,000 a year could easily become millionaires if they would only pare down their lifestyle to live on $12,500 (where would they live??).
Along the way, Collins sets up plenty of strawmen to make his points -- "smart people will tell you to sell in a down market" (really??) and "everyone laughs at index funds" (surely, you jest). Maybe those things were true in the 1970s and 1980s, but they aren't now.
All that said, I don't hate the premise of his book. If you want to know the simple path to wealth, per Collins, it is this:
1. The stock market always goes up over time.
2. Therefore, you should invest 100% of your money in a total stock fund.
3. If you are close to retirement, you can put 25% in a total bond fund.
For young people with decades in front of them, putting all your eggs in the stock market may make sense. But I pity the retiree who was all in this year and ended up locking in losses (even with a 75/25 mix) when making withdrawals.
I also take issue with Collins dismissal of Roth accounts, except for those near retirement. Why would you pay taxes on 40 years of gains when you can get them for free by contributing to a Roth at age 25? Collins uses that well-worn argument that a $5,000 Roth contribution would essentially require $6,250 when you considered taxes in the 25% bracket. However, that's just silly because no one pays their tax bracket rate. I thought maybe he didn't understand marginal taxes and effective tax rates, but he refers to them elsewhere so I think he was just ignoring them when it was convenient.
Overall, there is some good information and good food for thought here, but I just can't get past the delivery. Not only is his presumption off-putting, but this self-published book is a collection of blog posts so you get some repetition and a very uneven delivery. Some chapters are two pages; others are longer. All assume you have some knowledge of what he is talking about.
Collins is certainly wealthy -- at one point, he mentioned that while unemployed, he got tired of watching The Lion King on repeat with his daughter so he convinced his wife to quit her job so she could be a stay-at-home mom, presumably to allow him to do whatever it is that unemployed men without obligations do. However, there is no mention of whether his wealth came from investing or his previous employment.
So bottom line for me: some interesting ideas here, but I am not about to change my investment strategy based on the advice and experience of a single person.
