Margin can be powerful as a wealth building strategy, when interest rates are low. Risky? Yes. Profitable? Sometimes, if you've done your homework. I don't think you can be a consistent good stock picker, HOWEVER, there are certain companies you just know will do well because they're closely aligned to the industry you work in, for example. "Doubling down" using margin (borrowed at 1-2% per year, not 8-10%) can (maybe, sometimes, not always) be a good strategy.
