Hmm.. how about the expenses part? May be power of 0.X increase?
For guys, getting married could mean that you may have some "extra" expenses (Red and White matters in Hokkien) coming in as you now have MORE relatives; and may also get into the other family costs sharing matters (e.g. parental care such as nursing home cost).
Why? Son-in-laws are expected to contribute to the costs sharing matters especially when your wives are very generous.
