I've referred before to the idea of a "golden rule", the cynic's version: those that have the gold gets. It's also known as the "Mathew Effect", named by the sociologist Robert Merton from verses in the New Testament.
Saw another instance of it, from Hawaii where ProPublica reports that the "Homestead Program" (who knew we had a century-old program to provide homesteads to native Hawaiians) this:
But no one, not even the Department of Hawaiian Home Lands, the state agency that oversees the initiative, fully understood how far the program has strayed from its original intent. A first-of-its-kind analysis by the Honolulu Star-Advertiser and ProPublica of department data showed the program has benefited those with the means and knowledge to navigate the complex homesteading system while leaving behind much of the Native Hawaiian community it was primarily meant to help.
I suggest there are similar instances throughout government where the legislature passes a worthy program, but enrollment is required and there's an information gap, so some of those who might qualify simply don't know about it or don't know enough to navigate the hoops.
