For someone with $30K in annual expenditures that's lighting ~$900 on fire. And you lose extended warranty, return protection, etc.
What's wrong with a little self control?
When it comes to fiscal responsibility some people cannot exercise self control. Not a knock on them, just a fact of life. Not everyone was born into a family where they learned responsibilities or have the willpower or self control to handle their finances properly. Money management is a learned skill. It doesnt just come by osmosis.
I deal with people all day who were/are fiscally irresponsible to a point where it has seriously affected their lives. For most people in that situation its good to get "small" and give up all the trappings of life with credit for some stability and then, if the situation allows it, ease into new credit.
