FOR years, discussions of America's public markets have usually featured a lament for their dwindling appeal. According to Jay Ritter of the University of Florida, the number of publicly listed companies peaked in 1997 at 8,491 (see chart). By 2017 it had slumped to 4,496.

But the decline worries anyone who sees public markets as the best way for ordinary investors to benefit from the successes of corporate America.
