Realistically based upon the law of averages, lower middle, working, & lower class children won't go as far educationally nor socioeconomically as their solidly middle, upper middle, & upper class counterparts. It is highly likely that lower middle, working, & lower class children will remain in their original socioeconomic class despite people saying that there are such children who advance to the more affluent socioeconomic classes.
Lower middle, working, & lower class children are born severely disadvantaged w/massive odds stacked against them. First of all, they have less educated parents who don't have the knowledge to impart the importance of educational & socioeconomic achievement.The consciousness, ideology, mindset, & outlook of lower middle, working, & lower class parents is pure, rudimentary survival & nothing further. Such parents really inculcate their children to attain enough education to get a job w/security, no more no less. They may even imbue their children not to dream & aspire too high because they believe that their children won't achieve such unrealistic high goals.
Lower middle, working, & lower class children go to inferior schools where educational quality is second, even third rate.This puts them at a disadvantage when competing w/children from solidly middle, upper middle, & upper class backgrounds who attended superior schools.The former also don't have the monies to further their education.The best many can do is to complete their secondary education & to go to work from there. No matter how brilliant or prodigious lower middle, working, & lower class children are, they won't achieve phenomenal success levels because of lack of monetary access among other things. Such children do not have the connections that their more affluent counterparts have regarding job opportunities. Solidly middle, upper middle, & especially upper class children will always get the best jobs because they know more people in such categories such as their parents, other family members, friends, & associates. Lower middle, working, & lower class children do not have such connections among parents, family, & friends as people in specific socioeconomic classes associate among those particular socioeconomic classes, seldom, if ever venturing outside of such socioeconomic classes.
Yes,there are lower middle, working, & lower class children who advance into the solidly middle classes & beyond However, such are an extreme minute percentage.
