Based on prior knowledge, the marital status of an individual can provide some insights into their earning potential. Here's a thorough analysis of the relationship between marital status and the task of determining whether a person earns more than $50,000 per year:

1. Never-married: Individuals who have never been married might have fewer financial responsibilities, which could potentially result in a higher income. However, this group can include individuals who are young and just starting their careers, so there could be a mix of high and low earners.

2. Married-civ-spouse: This category consists of individuals who are married to a civilian spouse. Being married could potentially be associated with financial stability and a higher likelihood of earning more than $50,000 per year.

3. Widowed: Since widowed individuals might have lost their spouse, they might have a varied range of financial situations. Some may have inherited wealth or substantial life insurance, while others might have faced financial difficulties after the loss.

4. Divorced: Divorced individuals might have experienced a significant change in their financial situation due to the division of assets and potential alimony or child support payments. Therefore, the income level in this group could vary widely.

5. Separated: Similar to divorced individuals, separated individuals might also experience a change in financial circumstances. However, their income levels might be more uncertain compared to divorced individuals since the separation could be temporary or leading to divorce.

6. Married-spouse-absent: This category includes individuals who are married but temporarily separated from their spouse. The reasons for separation could vary, and the financial situation might be different from the other marital status categories.

7. Married-AF-spouse: This category represents individuals who are married to a spouse in the Armed Forces. The presence of civilians in this category might make it hard to predict their income level accurately.

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

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

In this dictionary, the "no" key represents the possible values of marital-status for individuals who earn less than or equal to $50,000 per year. The "yes" key represents the possible values of marital-status for individuals who earn more than $50,000 per year.
