Can you add more context?
I feel that record label owners have a greedy career. This is because the entirety of their business is profiting off of other people's talents. Someone comes in, record music, and if they become popular, the record label gets money. If the songs get sold or played on the radio, they also get money. It seems greedy to enter into a business where others earn one's money for them.
Children did not get the chance to go to school because they were constantly working. Owens said, "I want to learn, but can't when i work all the time."
Make a list of the main points you want to have in your presentation. Then work on researching them one by one. Search one topic at a time, find a RELIABLE resource, then find information related to that. Write it all down, then do the next one, etc., etc. Then you can filter out what you do and don't want in it, keeping the important information and ditching the rest. Then you can start putting your presentation together. :)
