Seems people seem to have a spending problems. And you don't need to cut it back fully to solve in in many cases. Just cut is back a little.
That said, when I was in my 20's and single I probably spent more than that per month because practically every meal was fast food, take out, or otherwise prepared in some manner. I suspect they could save a good $1,000/mo if they started cooking exclusively at home and paid attention to a budget while shopping.
McDonalds is surprisingly expensive if you eat it every day.
