No argument there about big business loving Hitler. He developed a permanent war time economy and went to war against his neighbors. War is always good for business until you start to lose and the enemy blows up everything you have.Germany did have a constitution with a bill of rights and checks and balances. It didn’t stop him. Hitler’s politics were anti-union and pro-privatization, which is why big business loved him.
But Hitler was a socialist and without war and neighbors to steal from, he would have not have lasted very long.
