Richest county in U.S. is 5 counties away – but you probably can’t name it

The richest county in the United States? It’s right here in Texas. But it’s not what you think. Sure, Houston-area Montgomery County made the top 50 (just barely), but it’s little McMullen County – south of San Antonio, northwest of Corpus Christi – that leads the way, as reported recently by Bloomberg.
