从这一段看，有可能的解释是

First-generation college students were more likely to report having starting salaries under $30,000 or unpaid positions. Despite making up only 15 percent of respondents, first generation graduates in the Class of 2022 constitute 30 percent of seniors who will be in the lowest salary bracket after graduation.

 

照顾进去的成分居多，所以，学一些容易的专业（大概正规的有难度的专业读不下来）。

毕业后很难在高薪的岗位上工作，选低薪的工作应该属于无奈，因为这类家庭肯定不宽裕。
