One word sums up our country’s achievements: miraculous. From a standing start 240 years ago – a span of time less than triple my days on earth – Americans have combined human ingenuity, a market system, a tide of talented and ambitious immigrants, and the rule of law to deliver abundance beyond any dreams of our forefathers.

You need not be an economist to understand how well our system has worked. Just look around you. See the 75 million owner-occupied homes, the bountiful farmland, the 260 million vehicles, the hyper-productive factories, the great medical centers, the talent-filled universities, you name it – they all represent a net gain for Americans from the barren lands, primitive structures and meager output of 1776. Starting from scratch, America has amassed wealth totaling $90 trillion.

….

Above all, it’s our market system – an economic traffic cop ably directing capital, brains and labor – that has created America’s abundance. This system has also been the primary factor in allocating rewards. Governmental redirection, through federal, state and local taxation, has in addition determined the distribution of a significant portion of the bounty.

…..

However our wealth may be divided, the mind-boggling amounts you see around you belong almost exclusively to Americans. Foreigners, of course, own or have claims on a modest portion of our wealth. Those holdings, however, are of little importance to our national balance sheet: Our citizens own assets abroad that are roughly comparable in value.

Early Americans, we should emphasize, were neither smarter nor more hard working than those people who toiled century after century before them. But those venturesome pioneers crafted a system that unleashed human potential, and their successors built upon it.

This economic creation will deliver increasing wealth to our progeny far into the future. Yes, the build-up of wealth will be interrupted for short periods from time to time. It will not, however, be stopped. I’ll repeat what I’ve both said in the past and expect to say in future years: Babies born in America today are the luckiest crop in history.
