I am off work today due to a "snow day" so had a little time to actually listen to the podcast was referring to and found about what i expected. Cardone over simplifies economic concepts to the point that his explanations are partially if not completely incorrect. However, the conclusions he reaches are by and large correct showing that he understands the concepts but does not have faith that his listeners have the capacity or desire to understand more detailed explanation.
Examples:
1. His grandmas bank account earned in the high teens in 1976 and earns almost nothing now which means traditional savings accounts are less valuable. - In reality the inflation rate in 1976 was 16.5 and is currently near 0. The real income from these accounts is almost exactly the same and savings accounts have been and will likely always be based on inflation + around 50 basis points.
2. The minimum wage adjusted for inflation is $2 less today than it was in 1960 so that means the dollar is losing value. - The minimum wage adjusted for inflation has nothing to do with the real value of a dollar. It is absolutely true that real income earned by the lower class has remained stagnant or slightly decreased for decades while the real income of the wealthy has increased significantly. However, this has no relationship to the value of money.
Cardone's ultimate take away that you should not just sit on your money but should instead invest it in something (namely real estate) is totally correct but not for the oversimplified reasons he stated. Investments unlike cash increase with inflation. Real estate investments allow investors to take advantage of leverage which increases the amount you can invest and therefore increases the potential profit.
Don't invest until you have $100,000 is another example of an oversimplification. People should have enough cash reserves to take care of themselves and their family if they loose their job and should have reserves built into an investment to withstand negative cash flow for a period of time. People should also not invest all of their savings in one investment that could serve to be life ruining if it fails.
It is hard to imagine someone having sufficient savings, cash reserves and the money for the down-payment on an investment property without having $100,000. The conclusion that you should not invest until you have savings, cash reserves and the money for a down payment is correct for most people. This conclusion does not take into account the complexities of the individual. A 25 year old with no family to support and a steady income can probably invest his first $10,000 in a SFH. He has less responsibility, more time to make up for a failure and cash flow to get through a tough part of the investment. A union member with fixed pension payments does not have to worry as much about savings and can probably invest with a much lower amount in the bank.
Finance and economics is complex and takes time and brainpower to understand. If finance and economics could be explained and understood in simple terms there would not be an industry of professionals paid handsomely for dedicating their lives to understanding it. Anyone claiming to be able to explain these complex ideas using a few easy to understand principles is selling snake oil and its important people take in this type of information with skepticism.
