Speaking about why we need minimum wage increases, any suggestions for where to start my research?

Hi, so this post is just about what the title says. I’m working on a speech for my college public speaking class of why the minimum wage has to be raised to help so many get by, does anyone have ideas for where I should start research on this topic? Sorry if this isn’t the right sub for this, been lurking here awhile and couldn’t quite figure out if it would be.
