I think it could potentially help you make better life choices, if you're aware of the economical situation. For example, what jobs to go for, what country to live in to maximise your income and pay the least tax.
It depends on the person though, to a more or less extent as for the level of interest displayed. I enjoy debating topics with people, it's interesting to learn views and perspectives of others.
However, I do feel that being exposed to so much negativity in the news can desensitise you... just because you hear about it so much! It's a defence mechanism. Do you feel that happening to you? I also feel like I sometimes need a break from the news as it can drive you insane! So, every fortnight or so, I'll take a break for a few days. However, in generally, I feel impatient to catch up with the daily news just as I like to be in the know of all juicy gossip. Do you feel you need a break from the news and politics?
