I'm not sure what environment you operate in, but spend a little time in an executive boardroom or on social media and you'll see just how much more important the brands and possessions that people own become as one gets older. I'm not sure how old you are or what your walk of life is, but there are reasons why people drive Mercedes Benz and wear Rolex and those luxuries are important to millions of people and admired by hundreds of millions of people. That's not "shallowness" (your word) but rather celebrations of success no different than a diploma or a promotion means to other. These are facts. They might not align with your specific morals but that does not mean that they are immoral or irrelevant.
Apple is a luxury brand making luxury electronics and they've been doing so for over 30 years. If you think someone with a $300 HP laptop from Best Buy isn't judging you and your $2,000 MacBook, think again.
Erm yeah at a boardroom if people look at your smartphone then I’ll probably not fit in that room.
A £50000 Rolex and a £1000 smartphone is not even comparable and all of them will have similar possessions. So what’s the point here?
Ps. I am part of a board by the way. Just to put in context.
