Building back better generally means tearing down what you have and replacing it with something worse. From the Zman at takimag.com:
That’s not true, of course. Nero would not have been so ridiculous, for fear the people would revolt. Like our modern tyrants, though, he conveniently had elaborate plans ready just in case things suddenly needed rebuilding. He rebuilt much of the city in the Greek style and built a massive new palace for himself. One of the features of his new palace was a 35-meter statue of himself called Colossus Neronis.
If the phrase “build back better” rings a bell, it should. It has become a strange slogan for the global political class. Joe Biden has a section on his campaign website labeled Build Back Better. In addition to the normal political rhetoric lies the claim that “this is the moment to imagine and build a new American economy for our families and the next generation.” Nero would have agreed.
New Zealand prime minister Jacinda Ardern used the slogan in her successful reelection campaign. “We will build back better from the COVID crisis,” she said during her victory speech. The fact that all of the damage done to New Zealand during the COVID panic was due to her dictatorial polices was not mentioned. Again, Nero would have agreed with her decision on that point.
