This isn't even about ideology; it's about limitations being exceeded on a global scale. That having been said, the ideology of market fundamentalism, and the ideology of fascism do have an alarming number of similarities. Both believe some should live, some should die; some should rule in opulence, some should toil in misery to support that opulent rule. They have different ways of deciding who is who, but in the final calculations it's usually the EXACT same people getting fucked.
