Does a marginal worker enjoy a rich lifestyle or live on a small amount of money?

A marginal worker lives on a small amount of money.

Explanation:

A marginal worker is someone that receives a small or limited income, therefore, there's no way they could enjoy a rich lifestyle.

Marginal utility of money is the amount of value (happiness) gained from an increase amount of money available to you. This value changes depending on how much you already have stache'd away. Put another way, the value I get from saving an extra dollar means a lot more than to a billionaire.
