everyone says to build a good business you have to find customers pain points and solve that, i agree but when i look at brands like coca cola, products like games, movies, all these dropshipping stores, expensive brands who outsource manufacturing and use the word luxury to price it way higher than market value of that product and still people buy it, what are they solving?
People like choices. You keep saying water. Why does wine, whiskey, coffee, tea, etc. exist. Coke is dominate due to them being one of the first colas to the market (unique), had a hard to replicate formula that gave them intellectual property (even without cocaine since it didn’t scale until that was long gone in their formula), capital since they grew due to being unique (and invested in), etc.
Basically, they built barriers to entry and own the top spot in the market. It’s VERY hard to dethrone a top player. Remember the coke sells a lot of other products also, including water. They also diversified when their sales were growing as quickly and/or slowed down in the past.
