I think you're reading "invest" more broadly than I am, and it's not unlikely that I am misusing a technical term, but I certainly do not want to be taken as arguing that debt is intrinsically bad.
Oh I don't look at usernames on purpose - I want to avoid falling into the traps of 'upvote/downvote because I usually like/dislike this guy's answers' and 'I have a mental image of such and of this guy because of previous posts, therefore this post must be correct/wrong too'.
Anyway I did read your post (and I'd argue, I read that reasonably) as saying 'debt = bad'. So if you're not saying that and only meant this particular investment, then I guess we're resolved our differences.
