Their objective is and has been to destroy capitalism. Socialism is how they will rule. It's not so much that Krugman and his fellow travelers are wrong as this is how they hope to seize power; Make things so bad people beg for government to take over.
Remember when JFK, a democrat, was more right-wing Constitutional than the RINOS of today? That man through guts and wisdom made the Soviets stand down during the Cuban Missile Crisis. He and his brother kept the World from blowing up. If there was ever a Kennedy that should have been put down, it was Ted. After LBJ, he did more damage to America than anyone I can think of off hand...and there have been plenty like Patsy Schroeder regarding our military.
