All this talk on wealth accumulation will never end. At the end of the day you will die. Why do you need to keep so much wealth until you die? Give to your kids and make them lazy? Why should you work so hard and all your wealth will be enjoyed by your kids. Stupid.
I would give the best education to my kids and send them to Ivy League universities. Then it's up to them to chart their own destiny. With the solid education, they can earn a lot more than I did and accumulate their own wealth.
I will just plan so that whatever wealth I have, I will spend it. I'll just buy annuities with my wealth. The payout will continue until I die.
