Based on prior knowledge, marital status could potentially have an impact on whether a person earns more than $50,000 per year. It is reasonable to assume that individuals who are married or have a spouse (either civil or in the Armed Forces) may have higher household incomes on average compared to those who are never married, widowed, divorced, separated or have a spouse absent.

Based on this analysis, the generated dictionary would be:

```json
{
    "no": ["Never-married", "Widowed", "Divorced", "Separated", "Married-spouse-absent"],
    "yes": ["Married-civ-spouse", "Married-AF-spouse"]
}
```

Please note that this is an assumption based on general observations, and the actual relationship between marital status and income would require further analysis of the specific dataset being considered.
