Tech companies love agesim. I worked at a large multinational for almost 20 years, and survived about a dozen "restructurings." Almost always it was the older people getting let go. Everyone knew it was ageism, and replacing higher paid workers with fresh lower paid workers. However, when they hand out severance, you agree not to pursue any litigation, and the severence was always generous. So, nothing ever gets done. I hope to be financially ready to retire by the time I'm 55, I'm 47 now, and on a good path. I'll still work for health insurance, but hopefully won't need to work for the highest salary.
