Interesting history, some of which I knew, but not that level of detail. But, I'm not sure how you can blame Carter for Reagan firing the air traffic controllers.
Rather than a question of blame it’s primarily an issue of inaction.
To reiterate, Carter administration knew very well about the strain moving from a point-to-point system to a hub-based regime would place on the air traffic controllers and failed to offer the adequate equipment/training to handle the increased volume:
By the time airline deregulation became law, FAA had achieved a semi-automated air traffic control system based on a marriage of radar and computer technology. By automating certain routine tasks, the system allowed controllers to concentrate more efficiently on the vital task of keeping aircraft safe and separated. Data appearing directly on their scopes provided controllers the identity, altitude, and groundspeed of aircraft carrying radar beacons. Despite its effectiveness, however, the air traffic control system required enhancement to keep pace with the increased volumes.
Furthermore, PATCO walked off the job operating under the impression they held leverage due to the sheer costs/resources necessary to direct flights using scabs and/or the military's resources. While air traffic slowed, the skies remained open in large part due to the aforementioned contingency plans the
Carter administration drafted in response to previous labor disputes:Before the 1976 presidential election, PATCO had sought to trade a political endorsement of Republican Gerald Ford for more favorable treatment. Rebuffed, it endorsed Carter in 1976. But Carter only made conditions worse, with controllers seeing the erosion of early retirement along with a decline in real wages. In early 1980, the Carter administration began to make elaborate plans for dealing with the air traffic controllers union. PATCO was aware that Carter was singling it out, and, for this reason, endorsed Reagan for the presidency after the latter assured the union that he would respond to its grievances.

Carter administration officials later publicly took credit for the PATCO union-busting operation. The plan was devised in early 1980 by Langhorne M. Bond, Carter’s appointee to head the FAA, and Clark H. Onstad, chief counsel to the FAA and also a Carter appointee. As early as 1978, Onstad began to work up plans for criminalizing a PATCO strike in discussions with Philip B. Heymann, Carter’s assistant attorney general in charge of the Criminal Division of the Justice Department.
The speed with which the FAA brought in replacement controllers under Reagan stands as a testament to these advanced preparations. At the beginning of the strike, the FAA academy in Oklahoma City suddenly increased its cohort from the typical class size of 70 to 1,400. Ray Van Vuren, director of operations for the FAA, said during the strike, “I knew we had too many (controllers) even before the strike, but it was impracticable to attempt to streamline the controller force because of expected resistance from the union.” If the controllers had not gone on strike, they would have faced as many as 3,000 layoffs.
“Incredibly detailed planning [went] on for more than a year because we just knew the strike was going to happen,” Onstad told the New York Times in the midst of the strike. The Times remarked, “Reagan administration officials enthusiastically polished and put into effect the plans first drafted in the Carter Administration."
These schemes cannot be explained on a purely fiscal basis. As PATCO workers noted, there would be enormous costs associated with training thousands of new controllers, to say nothing of the damage to the economy resulting from the inevitable restriction of commercial flights. The Reagan administration wound up paying some $2 billion just for the training of new controllers.
For Carter's part in particular, it was after all his appointed Fed chairman Paul Volcker who famously declared
"The American worker's standard of living has to decline." Volcker later gleefully cheered the PATCO firings as instrumental in
facilitating a borderline genocidal level of wealth inequality getting inflation under control. So while Carter left office in 1981, his administration's plans and own personal indecisiveness very much greased the wheels for Reagan's iron boot.
