Samsung Galaxy S5 spends more on advertisement compare to Samsung S...
The more they spend on advetisement the better, as this will generate bigger economy pie.
Developer Y spend on advertisement, Newspaper, Web developer, Property Forum, TV Station, Printer & etc earn more, then they spends on gadget, clothing, cars, grocery & etc, all this will generate a bigger economy.
Assumed Prody open a restaurant, he normally get 50 customer a day, each customer average spends RM 20 in 2007, Fast forward to 2014 Prody can expect 2 scenario.
1.) House advertisement remain same percentage 2% on advertisement cost, Prody Food now cost 3-4 times, unless Prody run charity or else no way his business can survived, since those who getting advertisement income from developer not earning more. so now Prody restaurant getting 15 customer but still spend RM 20 per head..

or
2.) House advertisement increase to 6%, Prody restaurant now get 150 customer per day spend RM 60 per head, for merely 60K Prody extra spend on a house he buy, now his business income also X 6.
So which one you prefer ?

Since we are dreaming I'll go for option 3.
House advertisement remains at 2%.
I only pay 20k for the developer to sell his house instead of 60k. The 40k I save I spend on:
1) 20k for direct advertising for my business. I now get 300 customers per day who spend RM 60 per head (direct advertising will have larger impact than economic growth).
