First, I want to establish that what I am going to refer to is Buddhism among what are essentially "converts" in the United States. This doesn't mean they dropped one religion and took up dharma (for example, I did not come from any religious upbringing) but means that they were not originally brought up as Buddhists. Further, I do not know what the situation is in other western countries, so my observations only refer to the United States.
Here are three observations:
1.There is a common belief that one should reject the material world in favor of spiritual pursuits.
This might be an attitude that came from from the 1960' counter-culture.
I would make a very random guess that quite often,
those who feel this way have had a materially abundant life yet found it not fulfilling,
as characterized by the saying, "money can't buy happiness".
2. Western buddhists are often reluctant to financially support the dharma centers that they are affiliate with,
and often feel resentment when asked to pay to attend teachings and so forth.
As a result, Buddhist organizations are often lacking in financial resources.
This is in stark contrast to Buddhists groups whose memberships are largely Asian to begin with,
and it is also at odds with Western Christian church organizations
which are able to get considerable financial support from their members.
3. "Spiritual pursuits" including the study and practice of dharma often manifest as ways of escaping the drudgery of having to make money, so whenever money issues enter the buddhist conversation, this threatens that escape mechanism, and people complain.
Profile Picture: "The Foaming Monk"
The Chinese characters are Fo (buddha) and Ming (bright). The image is of a student of Buddhism, who, imagining himself to be a monk, and not understanding the true meaning of the words takes the sound of the words literally. Likewise, People on web forums sometime seem to be foaming at the mouth. Original painting by P.Volker /used by permission.
