I finished reading the book and here are my final impressions
-the book is excellent for US citizens or residents. There is quite a bit of stuff in terms of savings money in fees, having access to interesting financial products (like special kinds of annuities) or tax breaks. For instance, I had never heard about special kinds of life insurance products that are tax free for accredited investors (and in same cases for small investors as well). these life insurance policies also enable the person to borrow against the plan and use the money in his or her lifetime. This in conjuction with Roth IRA's and Roth 401ks enable US persons to decrease the pretty ridiculous tax rates that they face. Its not so useful to me but for those living there its a must to know that these options are avaliable
Another cool product are some kind of special types annuities. If they are low fee, I believe annuities can be valuable. If someone wants to earn more than the risk free rate but they are unwilling to tolerate a big drawdown, an annuity would be like giving up a few % points in order to have zero volatility. The insurance company takes the downside because they trust that over the long-term they will earn more than they are paying out.
-The portfolios can also be very useful for US investors. The dalio portfolio (40% 20-25y USTs, 15% 5-10y USTs, 30% stocks, 7.5% gold and 7.5% commodities) might work for a US citizen who is willing to risk having subpar returns in case of inflation but for someone living in a riskier nation (brazil) like me, putting 40% in long-term government bonds is madness. Even long-term inflation adjusted bonds is risky (though its better than the ones that are not) because the government changes the inflation calculation when they run into trouble (as was in the case of Argentina).
They also offer some other portfolios for those who are more risk tolerant. The guru interviews were very short, he really abridged them down a ton, which is a shame. I would love to have them unabridged. All in all, its a must for those living in the US. For those outside, there is some good info but you must be careful not to apply the advice there without taking into consideration special risks or lack of tools you might have
