Obviously no one should starve, but someone who has actually worked for it shouldn't feel guilty for living in a big ass house and buying advanced amenities as long as they don't think of themselves morally superior to those with less money than them. The same theory would apply to anyone who instead of making a lot of money would pursue those "different things."
Of course not, I never advocated that they had to feel guilty for being successful in the business world. Saying "Well it's a dog eat dog world vv " doesn't mean that people deserve to live in fear of starvation and afflictions that even the most modest amount of money could prevent because they aren't business savy while others are surrounded by extravagance. It doesn't really apply to other aspirations in life since these things can't be shared nor are they required to survive, just make life worth living.
