How much do engineers earn?

If you are a non-engineer reading this site, your brain must've come across this question at least once. If you're thinking of becoming an engineer and everyone tells you that the financial prospects are very bright. Think again and do your research well.
I sometimes read the career queries section in the newspapers as well as on online forums and I see that a lot of people seem to have that question. And there are many wrong notions about it too.
There is stuff like - Could you tell me why do people in the medical field make so much money and not engineers?
Then there are the questions of "starting salaries" and "smart packages" and "per annum v/s per month". It obviously also changes with the country and the discipline you've chosen. Though I've firm beliefs that 'money' should be the last reason why you chose engineering, I think such questions need to be addressed. And where better than an engineering community.

So lets just talk about the major disciplines, Electrical/Electronic, Mechanical, Chemical, and Computers.
I invite all you engineers to share your experiences with the entry-level salaries as well as that for the experienced engineers. Let us see what each one of you has to say.
