why every doctor's bill is high does that medicine is that much costly?

Doctors are costly because they want to recover the investment on their education which in most countries is higher than other streams of learning like say Engineering or Commerce for instance. I would go to the extent of saying that it must be the highest. The second reason why they charge high could be as a reaction to the "delayed gratification" that they had to go through to be an experst in thier fields. It take s a good 10 -12 years of hard work and denial of leisure and enjoyment, to be counted as something in that galaxy. The second cause of Healthcare being costly has to do with corporatisation of healthcare. conceiving,Building and running, a corporate Hospital means a lot of investment and deployment of working capital. All this converts, what should have righhtly been a willing service to those in suffering to a basically heartless thing like business and dealing with figures like ROI, Break-Even and the like. The last thing that makes Healthcare, into a heartless business is the presence of the concept of Health Insurance. In another post (instalment)- as I need to attend some important business right now - I will post about why medicines are costly.
