For me the real problem of man is rooted from money. Most people wants to have more and they are not contented on what they have. They continue  chasing for money even  it involves illegality and compromising their principles in life. What is important for them is to gain more so they can buy whatever they want,  do whatever they want. Because they think they are powerful if they have lots of money. Money is not bad but if you love the money more than anybody else,  the problem begun.
