In my experience people are only going to explore those options and possibilities, for which the filters in their Subconscious Minds will allow them to perceive in the first place.
For example if some has a strong deep core belief that “XYZ is impossible”, then their Subconscious Mind will adjust their consious perception to filter out all the possibilities and solutions that go against this belief.
People could be in a library where there is only one book on the shelf that says “read me and you will know all the secrets of the universe”. And yet, most people would see the book with their eyes, read the title, and then, completely ignore it and leave the library… 
People will only discover those solutions to which they are open enough.
Even here on the forum, we have people who don’t believe in basic facts like aliens or the afterlife.
Subconscious beliefs heavily influece our perceptions and can make us literally blind to see possible solutions in front of our eyes if these solutions go against our deep core beliefs.
People with money, just because they have a ton of it, does not mean that they have an open mindset.
If they never really struggled in life, then maybe they were never motivated to question their reality and belief system in the first place, and thus, always stuck with the worldview that they adopted since childhood.
Most people usually never start questioning their life and the higher purpose of things until they hit rock-bottom. I guess this is because of the power of the ego.
They only way how to discover all the possible solutions, in my experience so far, is to make yourself deep down believe “that there must be a better and easier way to solve XYZ and that I am going to find it”.
This is the one belief that has helped me the most on my journey.
The belief that the universe loves you and that if there is an easier and more loving way to achieve something, then it will be shown to me and I will find it.
