Argumentative Research Essay topic?

My Argumentative Research Essay has to be 10 pages long with 7 sources(2 hard copy formats). My teacher had to approve our topics so I ended up writing the following two things down for him to approve:

“wage slavery” and “the need of Social Security or Social

welfare services”.

The problem is that I need to choose one of those topics and then form an actual research paper topic from it. Please give me some suggestions.
