Well engineer is definitely a low paying job. This is because the amount of effort and time, you chip in will never be tally. Nevertheless, the task can be tedious and nerve wrecking. That is why most of the engineer is bald! Not just that, engineer always face a lot of time and pressure to deliver a product to the client. Things will certainly get worse when there is a budget and time constraint to fulfill. Solving problem is also another task, which will be encountered from day to day. Problem can be complex and sometime can get very stressful if you dont have the skill to solve the problem. Last you also must be good in application for science and technology able to learn new things quick and fast under time pressure. I would say overall, Engineer is underpaid. ENGINEER = Professional Labour.
