What might be the long therm effects of ignoring ones duties? There are those who not only deny one's faults as a "Dhammic" approach, but  also are very anti-social (absence of gratitude and dutyfullness), with tendencies found in "I don't like people but I like buddhism" and certain answers. This attitude seem common given modern consumerism and individualism, yet ignores the fact that material goods have no goodness but are dependent on people's voluntary or forced sacrifices. 

So is it with some "Buddhists". There is no Buddhism without gratitude for people who sacrificed a lot that is not possible to repay. How can such an attitude of "I don't like people but I like 'food'" ever justify itself?

What might be the long term effects for people of such wrong views and trained to consumerism/householder-equanimity?

What will be the bill to pay, sooner or later, for grave wrong view?

In AN6.54 there was an ungrateful monk Dhammika, who craved solitude and was not hospitable to visiting monks. Eventually his kamma caught up with him and:


  Then the local lay followers went up to Venerable Dhammika and said to him:
  “Sir, please leave all seven monasteries in our native land.”
  Then Venerable Dhammika thought:
  “I’ve been banished by the local lay followers from all seven monasteries in my native land.


Because of his lack of gratitude and sense of duty, Dhammika was forsaken by all. 

Distressed and woeful, Dhammika went to the Buddha, who scolded him:


  “When someone abuses, annoys, or argues with an ascetic, the ascetic doesn’t abuse, annoy, or argue back at them. That’s how an ascetic stands by an ascetic’s duty.”


And Dhammika acknowledged his fault:


  “I was not standing by an ascetic’s duty when the local lay followers banished me from all seven of the monasteries in my native land.”


The Buddha then directed:


  But someone who abuses and insults a single person accomplished in view with malicious intent makes even more bad karma. Why is that? Brahmin Dhammika, I say that any injury done by those outside of the Buddhist community does not compare with what is done to one’s own spiritual companions. So you should train like this: ‘We will have no malicious intent for those who we want to have as our spiritual companions.’ That is how you should train.


These are some of the long term effects of ignoring ones duties.
