Walmart has to take many more risks and work much harder than mom-and-pop to keep its market share.
Walmart isn’t a person, in fact the person who started it and took the bulk of those risks to make out what it is has long passed. Yet a handful of billionaires his creation created still live above the rest of us while aspiring Mom and Pop store owners don’t stand a chance.
You’re right that it has to work hard to maintain its market share, perhaps you should ask yourself how it was able to attain that market share in the first place. It’s not because they were really just that much better than everyone else, it’s because the bigger you get the easier it gets to continue getting bigger. No, it’s not an absolute rule, which you will no doubt default to responding with, it’s a force for which individual results may vary but the overall trend is certain. As one billionaire put it, “turning one thousand dollars into two takes a great amount of work, turning a billion dollars into two is inevitable”.
