I recommend reading up and researching MLC...the key being is that the research is for your own knowledge. It really can't be used to influence or help the MLC'er....knowledge is power.
I think #1 should make you feel better. The same with #3...knowing the business side ramifications isn't bad IMHO. As long as it is for knowledge and not leverage.
I just don't get #2. I am trying..really trying...to understand this one. If you get a divorce...half of it is going to be yours anyways. Your wife might even try to pin it on you as leverage. I don't know...I just hate debt no matter what the reason. I hate even more paying interest on debt...or in other words paying for debt.
There is also a school of thought that says women feel less security in a relationship with excessive debt....granted that is a side topic to MLC, but it does make me think a bit.
