I don't disagree there are people who are capable of it, some people enjoy the simple life and I agree with your point that different people have different expectations.
I don't think we will never be able to understand each other. It's just seeing from a different perspective. It's not necessarily ego related. Like we are used to having toilets, what if you had to downgrade your lifestyle to the point where you don't have a toilet in your house, and you have to poop by the beach in the open? It's quite hard to do right? Maybe that's not a good example, but I'm just trying to illustrate how it feels to have luxuries you've had your entire life taken away. If you have kids in the future you'll probably also want them to enjoy the same luxuries you had if not better. Maybe a better example would be if your parents only made joint total of 1.5k a month, how would your life change. To people in that bracket, they would say, if I had 100k I would retire.

Anyway, this is totally off topic lol.

Luxury at this point only means better quality stuff. Not extravagance like buying lambos or some 500k watch. But yes you are right about people who are used to luxuries.
It sounds like we might be fairly similar in our current lifestyle situation. If your parents had 10mil now, 5mil your parents keep. 2.5mil to your sibling, and 2.5mil for yourself. Is 2.5mil enough for you to retire?
Your condo already costs around that much.

25k per month to support 4 adults, it is more than enough. To me, at.least.
But till all 4 die, that is hard to churn.

When you take into account your kids and nieces/nephews, their educations, even sending them to gov school and get treatment from government hospital, it will be just enough.
For 2 elderlies, 4 adults (you, your wife, your sister, her spouse) , 4 kids.
Unless you're living in Alor Setar or Kota Bharu.

There was one dude that converted to singaporean and flaunts his wealth like a year ago in /K...
He even show his account has more than sgd 10million...
Do u think he can square off against bapa kasi?

If you're able to do it and if that's what you enjoy and what you want out of life then that is great.

So daddy kasi got more than rm30 millions in his account?

That is something.

You are capable to upgrade, and downgrade, accordingly.

Not planning to have kids, then?

Yes. For 4 adults, it is possible.
I agree.
