I suppose there is a range of philosophical views, each equally valid where there is any degree of uncertainty. One of them is the one you espouse there; that it is all pointless as everyone is equally poor when dead. Another is that death is actually the end of everything, so you may as well have the best ride you can possibly get. What constitutes best is largely an individual thing so who's to say what is and isn't right or good. Once you add in the various religious views of life/after-life and even reincarnation, you have an imponderable range of outcomes with a bewildering array of routes to get there.Maybe. But you'll also die too, and what then? You'll also be brown bread and no-one will give a flying fück about your alleged "success" in life. The thing is that you can only be a "success" in life, but not in death. Is that really something to crow about? Really? Think about that!
Personally, I like a lot of excitement, considerable amounts of novelty, sumptuous comfort or even luxury sometimes and have been fortunate enough to achieve those things. Early retirement is not so far off and, judging by my current health and genetics, it is likely that I will see 90 at least. My appetites have not waned and I am really looking forward to it. I think that death is the end and there are no dress rehearsals, so I may as well have as great a time as I can on the way there. Obviously I am going to pay as little tax as I possibly can in order to fund this lifestyle.
Who cares what people say, do or think once you are dead (Apart from your loved ones obvs)? You will be dead.
