how much money does a manga and anime writer make a year? how much does an archetect or engineer?

Answer 1

A manga and anime writer like any writer doesn't have a salary. You sell a book; you get money. You don't sell a book; you don't get money.

As for architect and engineer, it depends on what field and the job's location. For more info on that visit: http://salary.monster.com/. It's a salary calculator/estimator which would better answer your question.
