What is the deep social meaning of "those who wear Luo Qi are not sericulturists"?

People who wear silks and satins are not people who raise silkworms and brocade themselves.

In other words, the people who worked hard to raise silkworms were still poor, while the rich wore clothes made by others, which satirized the social reality at that time. The poor live in poverty, while the rich live in luxury, accusing the society of injustice. Silkworm Girl, written in the Northern Song Dynasty, is full of satire and criticism of the society at that time. At that time, the feudal court, while wasting too much, compromised with foreign enemies, which increased the burden on the people and made life miserable. In this context, the poet described the experience of an ordinary woman who worked all day and didn't often go to town. She has been raising silkworms and selling silk for a living in poor rural areas. The whole poem is like telling a story: a woman went to town yesterday to sell silk, but she came back crying. Because she saw that people in silk clothes in the city were rich and powerful. Working people like her, even if they have raised silkworms all their lives, are unable to put on the "Luo Qi" ... This poem reveals the unreasonable reality that rulers get something for nothing, which is very convincing. There is no comment or profound association in the whole poem, but readers can easily feel the actual meaning of the poem and the poet's thoughts and feelings between the lines. Ancient poems fully expressed the author's dissatisfaction with the society at that time and expressed his deep sympathy for the working people.
