We live in a time of extraordinary promise. Breakthroughs in artificial intelligence, 3D manufacturing, medical science and other areas have the potential to dramatically raise living standards in coming decades. But a major obstacle stands squarely in the way of this promise: high and sharply rising government debt.

President Trump’s recently released budget is a wake-up call. It projects that this year, a year of relatively strong economic growth, low unemployment and continued historically low interest rates, the deficit will reach $870 billion, 30 percent greater than last year.

For years, economists have warned of major increases in future public debt burdens. That future is on our doorstep. From this point forward, even if economic growth continues uninterrupted, current tax and spending patterns imply that annual deficits will steadily increase, approaching the $1 trillion mark in two years and steadily rising thereafter as far as the eye can see.
