Offline or online job?

I was introduced to online jobs quite recently.  But I never take it as my main source of income, it’s just like a pocket money for me.  With my limited experience what I learned is that you cannot make good money only through online jobs.  You have to put more efforts than offline jobs.  But things may be different if you are really skilled like a medical trancriptionist or a software engineer. I read that they can make good money over net.

Moreover, in online earning there is no security and it is highly unstable.  You will not get any statutory benefits as in a regular offline job. There is no proper tracking mechanism in online jobs which makes  it more prone to become scams.

What are your views on both these aspects?
