All international conflicts, financial crises, can be solved without religion. To its separate members of society - yes. But it would not hurt a new worldview, where all dissonance from countless scientific, religious, philosophical ideologies would be solved, where everyone would be accepted regardless of race, social status, citizenship and so on. This idea could constructively unite people in a new worldview of the Future. Blavatsky tried to "form the core of the World Brotherhood without distinction of race, color, sex, caste and religion." It did not work, but work on this is still going on. Apparently hurry, people were not yet ready for this, the colonial system reigned. Of course religion is needed, but without coercion, religion helps to take a deeper look at our daily life and learn to live in unity with everything. A large percentage of people not religious has always been, it's not bad not good, just a given.
