I'm going to go down a different road here.
Yes, I believe that luck has something to do with "the easy life. But I believe that our life's course is often (not always) determined by a series of choices that start way back when we are children.
I came from an intact family, but not necessarily a healthy one. My mother came from a poor white trash family, had 10 siblings, and had a physically-abusive father. So she brought "baggage" to her marriage. But so did my father--he was the only child of German farmers and he was a "Mama's Boy" who never did break off the ties with his parents until they died. He also has an obsession with making money and I grew up living quite frugally so that he could invest his money in land and houses rather than in family activities. (Perhaps this is why I tend to be a free-spender--I am revolting against my father's unwillingness to give material things to his wife and children.)
But for the most part, my parents provided me with a safe and loving home. No one has perfect parents, and I learned to deal with their inadequacies and flaws.
When I think back on my childhood, I can recall hundreds of little decisions that I made that made life, especially school life, pleasant and "easy" for me. E.g., I wouldn't have dreamed of goofing off in school. I worked very hard and generally did much more work than the teachers asked for, even back in 2nd, 3rd, and 4th grade.
This good decision-making continued all the way through high school, college, and career. I made decisions that made it much more likely that I would eventually get a good job and enjoy a good life. I majored in a field that to this day, pretty much guarantees that I will have a good-paying job in any city in the U.S. (except California and Florida, where I have to have a special license.). No philosophy or English literature or religion studies for this girl!
Even continuing to play piano instead of quitting like so many other kids did was a good decision, because I supplement my income with piano gigs, and playing the piano gets me into social circles that are closed to many people in the community.
I believe that I made a good decision when I chose to marry the man who is my husband. He also made a series of good decisions as a child and teenager, and today he has a good job with an international computer company. If he should lose that job, his skills are in demand and he could probably land another good job within a fairly short time. There have been several times when he has sensed (because he is smart and well-trained) that his job within his company was in jeopardy due to trends in the marketplace, and rather than just sitting back and accepting the inevitable lay-off, instead, he worked harder within the company to find a different position that enabled him to keep a good job while his work associates lost their jobs and had to start all over. It wasn't luck, it was skill and intelligence and the ability to see what others, for some reason, couldn't see coming.
I could go on and on, but I hope that you see my point. My "good life" is not because of "luck." It's because of a series of wise decisions that started back in my childhood.
Yes, I have made some really stupid decisions that have brought me misfortune. E.g., I chose to gain a lot of weight starting in my late 20s, and this destroyed my knees and ankles and made me more and more inactive through my 40s. Who knows what other fat-related illnesses (breast cancer? heart disease? stroke?) are lurking in my body because of the bad choices I made thirty years ago? :(. Now in my 50s, I am struggling to lose the weight and try to gain back a lot of my lost mobility and health. Very stupid decision and I encourage others to please make good decisions about your health now.
I've mentioned in other threads that my husband and I made some foolish and irresponsible financial decisions that have put us in debt today. We should never have bought a house when we did--we should have waited until our babies were older. And when we did buy a house, we should have purchased a newer home in better condition, even though it would have meant a higher mortgage. Oh, well. At least our other decisions made up for this bad decision, as we are able to afford a "good" lifestyle as long as we are willing to stay in debt.
When I see others who are struggling with a hard life, I always wonder why? Something put them there. Perhaps I am presumtuous, but I'm guessing that if people take a good, hard, HONEST look back on their life, they will see when they started steering towards a course that brought them to a place in their life where they never seem to get a break. I know a lot of people who just never buckled down and worked during their school years, especially middle and high school, and then they never bothered to get any further education past high school (and if they did, they majored in something that would not provide them with a good job, or went to a technical school where they didn't get the kind of training that would get them in the door of a company), and then they decided that they simply couldn't move away from their childhood home (futher limiting their opportunities to find work) and then they decided to marry someone equally ill-prepared for life...anyway, I honestly think a lot of people would see that they really are responsible for the life they are currently living and that luck or fate had little to do with it.
