Adam Smith once wrote in The Wealth of Nations: Every prudent head of a household knows that if the cost of buying an item is less than the cost of producing it himself, he will not produce it himself. A tailor would generally never think of making his own shoes; he would rather buy them from a shoemaker. The reverse was also true: a shoemaker would rather hire a tailor to make his clothes. As for a farmer, he could hire a tailor to sew his clothes and a shoemaker to make his shoes, provided he had enough money.
After the magic show ended, Georgiana watched the well-dressed men and women who still had not left. It would not actually be that difficult to recover the stolen money Jeanne had spent. She had mainly used it to buy Versailles "necessities" such as clothes and shoes. They only needed to follow her bills and demand repayment from those luxury goods makers one by one. Even if they could not recover all the money, they could still reduce the losses.
Given Marie Antoinette's influence in the fashion world and at Versailles, she could simply issue an order: anyone who came to court wearing goods made by a certain tailor or shoemaker would be thrown out. To avoid such a scene, some people would stop wearing those clothes and shoes.
Those people now had a choice to make. They could either pay the money and remain in Paris, or leave Paris and seek opportunities elsewhere. All of Europe was copying Parisian fashion. These people who had once served the court might even fare better in some other small principality.
No matter how extravagantly Jeanne spent, she could not cause a migration on the scale of when Louis XIV revoked the Edict of Nantes.
