> Which means that even if the property only appreciates at the rate of inflation, your investment will grow faster than inflation.
Incorrect. You're also paying interest on the loan, which is usually pretty close to inflation. No matter how you slice it, you're pretty close to breaking even.
Also, you're not getting paid interest on the cash outlay you make the acquire the property, which is another loss.
> Voila: the power of leverage.
Leverage is just a tool you have, that can come back and bite you. If you leverage your investment by 10X, the real increases and decreases in value (adjusted for inflation) are 10X what they would be if you had not leveraged your assets. If you lose 10K of value on a 100k house that you put 20k down on, voila, the power of leverage. You just lost 50% of your investment.
> I'm not aware of any evidence that this is true.
The longer you go in your career, the less people care which school you went to because you have a work history that people can use to more accurately judge your productivity. If you're right out of college, your degree works as a proxy to that.
For most jobs, if you've already worked in the industry for 10 years, the salary you'll receive is roughly the same with and without a college degree, and the difference is even less between "good" and "bad" colleges. The earnings over career is a red herring, where right out of college, you get an initial salary boost.
