The millionaires at $1m to $10m absolutely DO have to be "frugal" if we use define "frugal" to be about "smart spending" as opposed to fishing pennies out of public fountains.
The word "million" is deceptive because it is an amount beyond what 99% have. It makes it seem like some mind boggling amount of money but mathematically, it really isn't that much. A person classified as "millionaire" could be tagged that because of total net assets and not the liquid cash in a bank account. E.g. a $500k house + $500k IRA/401k + $25k car is a "millionaire".
But let's say you have a multi-millionaire (e.g. 2 million dollars). That might be $1 million in cash in the bank. That's still not much money because:
- it's not enough to park $1 million of principal into risk-free US T-Bills and live off the current interest rates of - if your child gets an expensive health problem like leukemia or spouse gets cancer, your medical bills could blow past the lifetime cap of the health insurance policy and therefore, you have to drain your savings to pay for expensive treatments.
- non-Ivy League schools can cost $50k per year. If you have 2 children and you want to give them the gift of college education without being burdened with student debt, that's at least $400k. And to stay at $400k, it would require the parents to be "cheapskates" and not fund any extracurricular trips like ski vacations and Spring Break parties down in Mexico.
The millionaires that have less than $10 million definitely have to be "frugal" and watch their money. Consider than NBA star Allen Iverson earned $200 million and blew it all away.
At $100+ million, one can start getting frivolous and maybe buy a Ferrari. However, $2 million is not enough cushion to live off interest income and be 100% worry-free from unexpected life events. One would still have to work somewhere to keep adding to the nest egg.
