A life with no obstacles or difficulties is a very bland life, indeed. That's not to say we should seek tragedy, just that in every life, some rain must fall. It's all about attitude, and how you ride out the storm. Don't know if that's what you were looking for or not.
Everyone experiences troubles, disappointments, loss, and pain regardless of their station in life. Being wealthy just removes one of the major obstacles which keeps many from enjoying life. Poverty sucks! It tends to magnify our troubles. Even when one does have troubles it's great to be in a position to hire (the best) doctors, lawyers, or specialists to aid you. Just being in a position to jet off to a tropical island to recharge one's batteries and gain a new perspective is a wonderful thing. Oftentimes poor people invest too much time looking for an "upside" to being broke instead of ways to escape poverty.
I think money can solve a lot of problems in life, but not all..for example, someone who is very rich cannot buy real friends (they may have 'fake' friends who just want to be around them because of the money). Instead of pursuing wealth to find fulfillment, focus on the pursuit of meaningful experiences, and friends and family who genuinely care about you. These are the things that matter at the end of the day. Also, be smart about your finances (don't spend more than you earn, save and invest) so you don't get into any financial trouble.
