Who are the 1%? This doesn't answer your question, but personally, I don't think it's necessary to contemplate the philosophies of the so called "1%". What i mean by this is people in the 1% are essentially normal people who have vast amounts of power and money that corrupts them.
I would then ask you "do you think it is wise to follow the philosophies of these people?". Although, i'm not saying that all of these people in this category are corrupted, but that money and power may have an influence on these people that make them act in a less-than-virtuous ways.
You ever wonder why you constantly see rich and powerful in participating in scandalous activities? I would assume it is due to all the power that is influencing their thoughts and actions and makes them think they can get away with these things. There's also the fact that these people want to stay in their 1% position and will act in such ways to oppress the other 99%, in order to stay in their position.
I guess the point of this post is that their philosophies probably aren't the best ways to produce a better and happier life. Their lives just seem better and happier due to societies impression that obtaining wealth and power is the definition of success and personal fulfillment. However, I don't believe that this is the case. I would think that people who have learned that wealth and power are not needed for personal fulfillment would have the best life philosophies on how to reach personal success.
Although, this is just my opinion and is not necessarily the "right" way to think about it.
