Who are the other 1.75 million people who apply?

<p>In my job search, I ran across a TSA ad for employment and applied for an airport screener job. Then afterwards upon googling the TSA application process, I ran across the tidbit that the TSA received 1.8 million applications for the 50,000 intial positions that were open. Do Internet job sites normally receive applications in amounts like this, or was this just for this job? It also got me wondering that it is pretty sad that almost 2 million people applied for a job that only starts at $30,000 a year. I mean how many of these applicants had a real shot at the job? Any experiences with numerous applications for a position, or the types of people who apply are just are totally unhirable?</p>
