Well anyone who thinks anything declared in SALN should be taken seriously needs to be laughed at hard. No politician ever reveals the true extent of their assets in such a public document, just as no businessman would ever tell anyone how much their company is actually earning. In this country, honesty no matter how well-intended is never rewarded. If you show your true wealth, the crabs will call you "hambugero" or "kuwartag nawong".
The most laughable figure there is the declared net worth of Noynoy Aquino. Anyone who believes that figure should just be taken out the back and put out of their misery. I mean seriously!
This reminds me of a time back in college when they had a scholarship for the needy and the only requirement was to fill up a form declaring how much money your parents earned. Lo and behold everyone who "won" the scholarship had a Benz or a BMW and only won it because they misdeclared their parent's earnings. Long story short... You can force someone to give you piece of paper with numbers on it, but make no mistake, it is just a piece of paper with numbers on it.
