Which careers remain unaffected by ageism?

There are two categories of jobs that remain unaffected by age discrimination: Politics and self-employment (e.g., freelancing, artistic career, etc.). Generally, if you’re old, you have fewer chances to get employed or selected for the job you want. But in politics, being older is considered a bonus. However, musicians and artists are less prone to ageism, mainly because they are their bosses. Also, jobs requiring specialized knowledge or experience in a specific field do not usually suffer age-related issues. I’d mention doctors, lawyers, university professors, teachers, accountants, and investors, to name a few. I hope it helps.
