Final answer:
Age discrimination, specifically against people under age 40, appears to be the group that experiences the highest level of job discrimination.
Step-by-step explanation:
Among the groups listed, people under age 40 appear to experience the highest level of job discrimination. Age discrimination, also known as ageism, is a common form of discrimination in the labor market. Research has shown that older adults are often perceived as incompetent, physically weak, and slow, leading to age-based discrimination in access to health services and work opportunities. In contrast, younger adults may face stereotypes of being immature and irresponsible, which can also lead to discrimination in certain job positions.
