The positives of the older, low fee LICs I feel are very well known and covered. I personally think they have been excellent investment products for so many for such a long time. I particularly like the positive influence they have had on investors helping them with the behavioural aspects. i.e. sticking the course and seeing the benefits of compounding, highlighting dividend returns and benefits from not overtrading, including taxation benefits.
Now for the section where I might receive some negative feedback!
