> It's true that some people need to purchase items on credit but the reason that they're so popular now is less to do with having a line of credit and more to do with the legacy of the technology. I don't know if that is true. My wife and I make a fari bit of money but we use credit cards so we don't have to worry about cash flow. If I want a new mac I just go out and buy it. I don't have to worry if I have enough money in my account at that exact moment or not because I know that at the end of the month when the credit card bill comes I"ll have enough to cover it. We might be an exception because my wife divides our income into several buckets as it comes in and then pulls from those buckets to pay the credit card bill at the end of the month, so I know very well what my monthly budget is . TL/DR we use credit cards as a line of credit to smooth over cash flow throughout the month as do most afluent people I know.
