Seven years does seem a long time, but leaving the exact period aside, counselling allows someone to share their feelings with a private but objective person who has been trained to listen (and most people in the UK aren't good at listening).
As someone up the thread has said, before there were counsellors available, people went to a vicar or priest (who might then abuse them!) or they distracted themselves by beating their wives, kicking the dog, getting drunk, over eating, beating their children and generally being bitter and difficult to others.
There are many types of counselling and many types of problems. I really don't think you can generalise. There is also the question of resilience which may be down to personality, circumstances, having someone, just one person, who cares for them in childhood or other resources (such as a reasonable income) which help them to feel content and able to find a job and live a normal life without abusing others.
We've got huge problems with pornography, child abuse and loneliness in this country, I don't think deciding there's something wrong with people who ask for help and use counsellors is very useful.
