OK, I just HAVE to weigh in on this thread.
As always, I have many opinions (who me, opinionated?
yep). Some of these opinions may not be all that popular but here goes:
My views are that someone who has achieved bliss, contentment, nirvana, or whatever you wish to call it, in life, does not have a duty to toss it out the window and engage in hyperconsumerism when they are already content.
If someone is already content, it seems to me that very little enjoyment can be had from just spending more money on things/experiences for the sake of spending it. Sometimes not spending can provide more enjoyment than spending. Sometimes the greatest new experiences are free. Sometimes extra things are just an albatross.
I see zero reason for someone who is content to feel obligated to spend everything they've got, even though they do not find doing this is necessary for further contentment, so as to not have a penny left when they die.
My thinking is that it is not immoral to leave money to one's heirs, or to charity, and at the same time to ensure that one has enough money to live to over 100 years old without depending on someone else's tax dollars.
Now, on the other hand, if someone is truly NOT content, then that's a different matter.
* If you always longed to, say, go on a photographic safari in Africa, and can afford it, then do it while you're young.
* If you always wanted a Dream House and can afford one, then buy one and move (and hurry up with that too - - moving before you're 65, in my experience, was a whole lot less exhausting and stressful than moving after 65).
* If you want to travel by RV before you die, then by all means buy a nice one if you can afford to do so, and take off! Again, this is probably better done while you are young enough to see well and drive safely.
And so on. But if you would rather just stick with the status quo, there's nothing inherently wrong with that either. Just make sure that is really what you want, and that you are truly content.
