And? What's wrong with that? There's no free lunch there - they still have to pay back the loan. It's not like it's free money.
Of course, in a ZIRP fantasyland the interest is negligible.
That would be insane.
I guess it’s a bet you’ll be dead before the interest outweighs the potential tax, or volatility spikes? Betting on your own death seems to macabre, and too tempting too the fates.
Over the long run it tends to work in their favour as well, since it's very likely that the increase in the portfolio value will outpace the interest paid.
Ah, right. Caught me twice on my fixed-pie thinking :)
And yes, a bet that interest rates will remain below effective tax beyond that.
