Why should one aims to have $100,000 by 30??

There are those who feel that "die die also not possible to have $100,000 by 30... and start thrashing that one needs to 'enjoy' life, have 'quality' life... thus all the calculations is rubbish and impractical.

Those who have managed to clinched the 100k deal by 30 must have been lucky enough to have silver-spoons lying around for them.

Is that a fact or is that an excuse for one not to save?

Maybe a scary peep into the life after marriage, esp with a child will encourage one to exercise financial plannings. (well, at least this works for me)

ASSUMING

1. "Re-calculated" monthly expenditures (after marriage): $1250 - $1650+++

[PERSONAL: $300 - parents, $100 - insurance, $50 - hp, $200 - transport, $300 - meals, $150 - misc]
[ONE TIME: all the *bling bling*, wedding photo, wedding dinner and the list goes on... AND furniture for new place]
[HOUSEHOLD, SPLIT WITH SPOUSE: $30 - conservancy charges, $25 - internet, $80 - electricity, $15 - housing tax + renovation loan(?) + cash top up for housing(?)]

[CHILD, SPLIT WITH SPOUSE: $50 - insurance, $50 - endowment, $150 - food, $150 - misc, excluding birthday celebrations, tuition, childcare, enrichment classes, maid, upgrading of educational equipments ... ... ...]

[*touch wood* as parents get older, you know... visits to doctor starts getting more and more frequent... they need more supplements, more therapies... it's all money. :(]

*sings* 'price tags'

Imagine if both you and your spouse have had this goal, combined savings upon 30 will be: $200,000. 

Then maybe $100,000 can be used to offset a lot of the above items... so tt the marriage won't be plague by the mountains of loans / debts ... its a 'ripple-effect'... Is it not?
