So you can imagine the United States is continuing to run a deficit- it's continuing to spend more than it brings in- and actually for the United States these ratios are appropriate, for every dollar that the United States spends 40% is borrowed, it only has 60% of every dollar it needs to spend right now, so it needs to go out into the debt market and borrow 40% to keep spending at its current rate so if it's continuing to borrow, you can imagine that the debt keeps on increasing.
