Which kind of ageism is most common?

Unlike racism and sexism, age discrimination is a socially promoted bias. Ageism in hiring is only one example of how elders are mistreated, and it’s the most common, in my opinion. And it is often those from Gen Z to Generation X who do it. And it is in the form of a patronizing, condescending, sickeningly sweet tone in the presence of anyone with wrinkles.
Once you hit 50, the number of jobs you will be considered for decreases significantly. At 60, you become pretty unemployable except for positions that others with equal education and experience (but younger) would never consider doing. Societies are wasting an abundance of intellectual wealth and wisdom by ignoring the value of hiring older people. It’s a sad reality that is a loss for everyone involved. It is not only tragic but very disheartening and demoralizing to those who are recipients of such bias. Many could continue to make significant contributions to the workforce if given a chance. Unfortunately, I don’t believe it is going to change anytime soon. Sadly, it’s impossible to prove that you have been a victim of such bias, but it’s ordinary in every industry. Age discrimination is generally tolerated because the person discriminated against does not have many options.
