In "A Roadside Stand" by Robert Frost, the poet uses words and phrases to illustrate the double standards of the government and social service agencies. Here are some examples:

1. "municipal rubbish" - This phrase suggests that the government views the products sold at the roadside stand as inferior or unwanted, implying a lack of respect for the goods and the people who produce them.

2. "cheapest form of pride" - The poet describes the roadside stand as a symbol of pride for the rural people who operate it. However, the use of the word "cheapest" implies that the government and social service agencies do not value or recognize this pride, undermining the dignity of the rural people.

3. "pitiful and farcical" - These words convey the poet's criticism of the government's efforts to assist the rural poor. The use of "pitiful" suggests that the assistance provided is inadequate and deserving of pity, while "farcical" implies that it is absurd or laughable in its ineffectiveness.

4. "Weeds in a garden" - This metaphor compares the rural poor to weeds, implying that they are seen as unwanted or undesirable by society. It suggests that the government and social service agencies view the rural poor as a nuisance rather than as individuals deserving of assistance and support.

5. "Who would be scorned by / The quieter types of city folk without an hour / To waste on talk of the better kinds of rural work" - These lines highlight the disdain and indifference of the city folk towards the rural poor. The phrase "scorned by" suggests that the rural poor are looked down upon and discriminated against, while "quieter types of city folk" implies that even those who do not openly express their contempt still harbor negative attitudes towards rural labor.

Overall, these words and phrases used by the poet serve to underscore the double standards of the government and social service agencies in their treatment of the rural poor. They highlight the lack of respect, recognition, and support given to rural communities, as well as the dismissive and condescending attitudes of those in positions of power towards rural labor and livelihoods.
