We're just about to settle on our 4th investment property which will put us over the million dollar mark (and plan to buy more). Doesn't worry us because they are all neutral or positively geared so don't cost us anything and if we had to sell they would pay off what we owe. Won't be debt free for a while until the equity is eventually enough that if we sell a couple we can pay off the rest and get the income outright.
We don't go into debt for cars and have no CC. If we did I think I'd be a bit more worried and want it paid off as quick as possible.
As pp has said, there's a difference between "good" debt and "bad" debt and any bad debt we try to avoid or get rid of ASAP!
