In Li Sao, why did Qu Yuan "lament the hardships of the people's lives" and "at the same time"?

Li Sao is a political allegory poem, which Sima Qian said was written because of political dissatisfaction and resentment. The poem talks about politics, makes metaphors, flatters the people trusted by the King of Chu, compares the trip to Gao Jie with herbs, and compares Chen Junzhi with love. There is no mention of people's livelihood from beginning to end. The so-called "long breath hides tears, mourning people's life." I just lamented the hardships of life.
