I think you have been told several times what the problem was.

The trouble with this question is that it is location specific. In some countries the postoc will pay higher taxes and get health coverage. In a few countries, the university needs to cover the cost of health insurance and that is generally passed on to the PI. There will be variation between universities in the same country. The current question is very broad and probably will gather misleading answers.

It's usually a good idea to give a reason [why you are asking the question] because many questions on this site come from flawed premises, and the most helpful response is to correct the premise rather than to literally answer the question.
Finally, I wrote:
Most open/close decisions here are made by community vote, not by moderator fiat. If you edit your question, it will be placed in a queue for a reopening vote. The hard part of question-asking is the amount of detail: it should be specific enough that there is a correct answer rather than an open-ended discussion, but general enough that future readers might find the question useful. In your case, a good starting place would be to specify your country (or part of the world) and field.
Now I see that you have added a location, which is good, but still no field (even a general field, like laboratory science vs. history) and no hint of why you want to know the answer. You may feel that we can provide a good answer without knowing these variables, but the community apparently disagrees.
I replied appropriately to these condescending, patronizing comments
Let us be honest about what happened. You told one of our most respected members "haha oh lord, how can people be so anal?" You also wrote "Due to bullying and peer pressure, I have unnecessarily reduced the scope of the question. Hope you are happy now? Or should we waste our time making it more precise?..." Even in this meta post, you call us condescending, patronizing, spiteful, and childish.
This is against our code of conduct (which a moderator pointed you to). We do not allow "subtle put-downs or unfriendly language." If you feel that other members were unfriendly toward you, you should flag for moderator attention rather than responding in kind.
I will also point out that some of our members have been here for years, helping thousands of people with no reward. In contrast, you have been here for two days and have already unleashed a barrage of personal attacks. As in "real life," you will seldom be able to advance your agenda when you make others defensive and hostile.
[How to move forward?]
You did the right thing in posting to meta. Setting aside the above issues, I actually agree with you that this was a straightforward question that got "massacred." It is true that things will vary school-to-school, but I think your request for a "ballpark" for a particular country and field is very reasonable.
So, my suggestion would be that you edit your post to specify a particular field (e.g., history or experimental chemistry) and then we reopen. Explaining why you want to know would probably lead to better answers, but I wouldn't consider that mandatory. But this is just my suggestion, not an "official decision" -- we will see if any other community members respond to your post with other suggestions.
