A historical analysis by Postel-Vinay and Rosenthal reveals the persistent concentration of wealth in Paris. The French capital shows a pattern where property and capital accumulate among an elderly elite, favored by housing policies and hereditary transmission. This scenario contrasts with the conditions of the young population, who face stagnant wages and a high cost of living, calling into question the sustainability of the pension system and intergenerational equity.
Modeling historical data to forecast pension crises 📈
The study's methodology is based on processing large volumes of historical tax data, dating back to the 19th century. Using time series analysis algorithms, models are built that trace the evolution of asset concentration. These simulations allow for projecting future scenarios, demonstrating how the current architecture of the system, with its wealth bias, functions as an algorithm that amplifies inequality. The technology shows that the problem is not one of resources, but of distribution coded into the system's rules.
The pension sim: playing as a rentier on an intern's salary 🎮
The situation is reminiscent of a video game with extreme difficulty and inherited saved games. New players start with debt instead of resources, while veteran avatars, controlled by inactive users, accumulate wealth passively thanks to unbalanced game mechanics from previous patches. The tutorial doesn't explain the real rules and the only available quest is to pay the tavern's rent. Achieving the good ending seems to require a generational glitch or a complete server reset.
