Do not be naive... :angel:
That is sort of the information no one will tell you
Everyone is afraid to tell their income. Because there may be someone earns better than him.
In my point i don't have to say anything. Because i don't have any static monthly income.
Why would I be afraid to tell my income? Do you tell everyone your income in real life? Do you walk up to someone and say "hey, I make $8 an hour!" or "I make $6,000 a year!" I'm pretty sure no one does that, as its confidential and the only time you really state something is for taxes or credit purposes.
Your point is fair. But in my view, the income is not really confidential. Even 5 more people know about your income.(parents, friends etc....)
In my opinion, most people may get offended if you tell them. If you make too much money, people might try to ask for money or take advantage of your situation. Just my two cents.
