How is Materialism in Society and Metaphysical Materialism connected?

[MM1988]

In which ways are Materialism in the form of chasing wealth/external goods/fame and philosophical Materialism in the form of belief in an external world connected?

Without being materially prosperous none can realize the uselessness of prosperity, without getting wealth, none can know that nothing is achieved by wealth. The greatest gift of wealth is the disillusion about its worth. If one does not get wealth, one can never know the worthlessness of wealth. The distressed, the needy and the poor will find great difficulty in being free from the lure of riches. How can one be free from that which one has not got. To be free from a thing, one should have it. One should have the thing first, then and then only can one be free from it. 

When everything is collected in the world outside, but there is a total void within. These are moments which begin the metaphysical materialism.
