What is often associated with extreme greed for material wealth?

The term that is often associated with extreme greed for material wealth is avarice. Avarice refers to an insatiable desire for accumulating wealth, to the point where it can lead to unethical behavior or a lack of concern for others. This concept embodies not just the desire for wealth itself, but also the negative connotations that come with prioritizing material gain over moral values or human compassion.

In contrast, generosity and philanthropy involve giving and sharing wealth for the benefit of others, which directly opposes the self-serving nature of avarice. Contentment, on the other hand, signifies a state of satisfaction and acceptance with what one has, further highlighting how avarice stands in stark contrast to feelings of fulfillment without excessive desire for more material possessions. Thus, avarice is distinctly tied to the notion of extreme greed, making it the most fitting choice in the context provided.
