Why is that after many years people come forward with allegations/accusations against the catholic church?

Please answer me in a polite and constructive way,I just think that there may have been some cases where there was nothing involved except money. I mean when I was 5 if someone touch me , my parents taught me to speak out, Is it just me? And do people forget its not just catholics ? again this is not meant as a insult but a Serious question. your thoughts?
