What makes a difference for further advancement of engineers: socioeconomic background or education programs?

Education is considered to be the most effective tool that people can use to lift themselves out of poor socioeconomic backgrounds and lead to professional success, which in turn improves society. Since an education system often supports individuals with a higher socioeconomic status (SES), it may not resolve the issue of socioeconomic background impacting on career outcomes. Given the nature of the research questions, an individualistic approach is used for selecting tools.
