well.......actually say it like this:
the key point is not the industry, but the salary and hours: it is very rare that a "normal-working-hour" job will pay high enough to make the MBA tuition a worthwhile investment.
Finance and Consulting are just two common place that stress the employee and pay well, as an example.
therefore if really like "平静,想早点结婚生孩子", then better not go for an MBA.
a too huge investment, while the return have to be earned through really long-hour work.
