In the US, the average age of the population is higher, and people above the age of 40 form a significant part of the population, making it easier for them to get justice
In contrast, in India, the government is openly discriminating against older people, refusing to listen to their complaints, while openly pampering and rewarding younger lazy liars and frauds.
So in India almost no one is filing age discrimination cases, especially against larger companies, since the companies will destroy the life of the person filing the case, subjecting the person to organized stalking.
