I think Buddhism can be quite useful for lay people to develop mundane wisdom and being more peaceful than the average human being. This also should have a positive effect on our relationships.
Aiming at the supramundane is quite a different story and the level of seriousness needed (as i imagine it) is beyond the capacity of most of us and most definitely beyond the games we play with ourselves. These games can take numerous forms including making sacrifices.
The more we become aware of our own superficiality and limitations is the better. That would help us avoid a lot of pitfalls along the path. All in my opinion.
Balancing family life and the Dhamma, in pursuit of a happy lay life.
