It might be like that. Everyone should strive to make the best decisions and not go with the mainstream. Always question the mainstream, it's dangerous. Make a change for the better. Everything starts with you. Then your family, friends, neighbors...
Do you have the opportunity to grow something yourself? Do that.
There's some value in that line of thinking, as the mainstream often (okay, euphemism there) pushes bad choices, like in the past smoking being mainstream to the point of doctors being paid to promote the "health benefits" of cigarettes.
But at the same time I don't think its healthy to _always_ question everything in the mainstream. Its mainstream for a reason (sometimes an angle pushed by economic groups like big cig in the example above), and sometimes the reason is reasonable. Be critical and keep an open mind, but don't assume its fake because its mainstream.
