Again, back to subjectivity. You said "he focuses his energy properly." Who is to say what is "proper." Tribes in Africa focus their energy on harvesting and hunting food. They focus on survival. You have to be pretty wise to stay alive when faced with such extreme conditions. Most tribes in Africa can't spend their energy as the Dalai Lama does because they might not have the resources or time. Does this make their energy purposeless? Or does it make it different? In their opinion, their energy is purposeful. Is this okay for you? Or do you just have something against the way Americans live (fucking, lifting and drinking)?
You can meditate and be conscious while hunting, or farming, or working or anything else. You can be conscious and turn anything into a meditation at any time.
But, 99.99% of the people out there simply don't do this unless they are on some kind of spiritual path guiding them to do so.
Many hunter-gatherers are very wise a spiritually evolved because they do not have the trappings of the modern materialistic world like we have. Internet, clubs, TV, Youtube, Ipods, neon signs, traffic, etc. etc. The are just living in a more quiet and natural world without overstimulation of the senses and it's more conducive to introspective spiritual endeavors.
