Judging from my very own current problems, I guess I'd start to support small universities and support promising young students, especially if they study some sort of had science like physics, math, computer science and such.<p>Such support should include money (well, students need food, books, other equipment depending on the course), but I think it should also include support with various buerocratic problems, like facing the german bafoeg-institute and other buerocrats.<p>Certainly, it will be hard to actually get a good selection principle going and it also needs a plan to get the money back, but once this is done, I think this is a very valuable thing to invest in. I mean, studying is pretty much a full time job (well, if you study hard to get through the universiy fast, it is), and thus, students usually don't have that much time to work and sometimes they even get to pay for being at the university.<p>Besides that, I would invest a large sum into neurodermatism research, just for pure egoism. I have this problem, and whoever also has this problem knows how bad this status can be whenever it goes active. (To everyone else: Just imagine the urge to scratch your inner elbow, hand or other inappropiate locations until every skin is gone and just a bloody mess is left. After that, one is depressed, cannot move properly and is in pain.) Thus, this would be a second major investment. I guess it also would not be that egoistic, as a lot of people could benefit from results from this research :)
