Maybe "taken advantage" isn't quite the right word here. But it's one of the ways in which the rich get richer faster, because they take more advantage of nominal debt to acquire real assets.

I see too many people in my own social circles who are very anti-debt, which is fine if it was an informed point of view, but it's usually not--they're just taught to be afraid of debt, not because it's a decision made with an understanding of the tradeoffs.

IMO the way you think about this stuff matters, because it bleeds into policy. For example, I don't support the 50 year mortgage because the risk is borne by the taxpayers; not because it's a bad deal for the borrower. If you make it about being a bad deal for the borrower (which it's not), then you miss the more important objection.

They'll be lining up for different reasons. The struggling Joe lines up because the 50 year mortgage is the only way he'd be able to afford the monthly payments on the house. The rich guy lines up because he knows that it's a great deal to extend nominal fixed rate debt out for 50 years.
