No, it's fine. They could lose their income, but still pay off all those things that are financed and pay them off because they "have" the money, but just chose to finance... To, you know, get a higher credit score or get some 1% rebate or something.
Give me a break.
If you are paying on it, you don't own it. That includes stuff you pay for with a credit card. I don't care when you pay it off. All of those points and rewards do the square root of fuck-all to your net worth. I'd go so far as to say they will ultimately negatively impact it.
But what do I know... Apparently I'm the one that can "control myself" with money enough to borrow from a third party for something I could just pay for in cash. I seriously LOLed at that.
Young guys: if you are reading this thread, you are trying to maximize your income to secure a comfortable retirement. Owing people money, even for a "short" time and even if you can "afford" it does not contribute to your net worth. Millionaires don't get to where they are and say, "Man, those credit card rewards really helped me get here." They got there by living within their means, which means they did not BORROW MONEY.
It continues to blow my simple mind as to why this such a difficult concept to grasp.
