DO NOT let lack of money dissuade you from what you want to do. That breads resentment and bitterness. Do it, do it well, and the money will come.
I went to MIT. I hate it when people assume that you have to be rich to go there, or make comments like "my parents couldn't afford that." That isn't a reason to not even try. I'm not sure about the original poster's financial status (upper middle class can be a big range), but MIT recently announced it will be tuition free for those families making $75000 or less.
And the name does make a difference. I got my first job due to it (poor match in the end, but that is another story). Many employers see it as a short cut to the type of person you are. You *will* get a good job if you went to another school, especially if you are good (goodness will always override name in the end), but as other posters have mentioned the fact that you are surrounded by smart and clever people kicks your own performance up a notch. Being able to see exactly what you are capable of and find and notice your limits is an amazing experience.
I wouldn't trade my time at MIT for the world, despite 4 years of complaining about the workload, the pressure and the frosh.
