You make a good point that the next World War or Great Depression remains inconceivable to most of us despite either one or both playing out in the next 50 years having a high probability (we may even be in the beginning stages of a Great Depression and just not know it yet). While we agree on that subject, we may disagree about Starbucks being overpriced.
More so than overpriced (because I would gladly pay three dollars for a real latte and another dollar to tip a real barista), Starbucks is oversized, substandard, and inauthentic. This is what a real latte looks like. Oscillating waves of crema and microfoam bring out the subtle flavors of the coffee (a perfect pull will taste as good as it smells) and the sweetness of the milk (you don't need to add a syrup or sweetener when milk is properly textured). Starbucks becomes unpalatable once you've been to a real espresso bar like Espresso Vivace in Seattle. You know, I wouldn't consume a Starbucks beverage if given to me for free (haven't been there in years and the last time I bought juice). Honestly, you would have to pay me to drink that shit. Hmm, so maybe we do agree that Starbucks is overpriced.
For God's sake, stop researching for a while and begin to think!
