Marital status can be an important feature in determining whether a person earns more than 50000 dollars per year. In general, individuals who are married tend to have more stable income sources and potentially higher earning capacity. However, the relationship between marital status and income can vary depending on other factors such as age, occupation, and education level.

Based on this analysis, the dictionary can be constructed as follows:

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

The "no" list includes individuals who have never been married, are divorced, separated, or widowed. These individuals might not have a stable income source or might have lower earning capacity. 

The "yes" list includes individuals who are married. Being married is generally associated with more stable income sources and potentially higher earning capacity. It includes categories such as "Married-civ-spouse", "Married-spouse-absent", and "Married-AF-spouse".

Please note that this analysis is based on general observations and there may be individual cases where the relationship between marital status and income might not hold true.
