The Deficit Problem in a Chart

The most important thing to understand about the U.S. budget, Donald Trump or no, is illustrated by the nearby chart. Even with Mr. Trump’s modest increases, defense barely rises as a share of federal outlays. In 1989 when the Berlin Wall fell, defense was 26.5% of outlays. In 2019 it will be 15.6%.

Meantime, look at “payments for individuals,” which encompass such income transfers as Medicare, Medicaid, Social Security and food stamps, among other things. This category was 47.7% of outlays in 1989 and has steadily climbed to reach an estimated 69.2% in 2019.

.. Net interest on the federal debt soaks up another 7.4% of outlays for 2018, and that will rise with interest rates.
