I wonder how many people out of 2 billion could be fed w/ 2k. Or even what's cashed in from Lowe's in scrap metal. Since you care so much about the hungry & obviously don't need the money, I'm sure I misunderstood your intentions and in fact you plan on donating the reduced (after Lowe's, after the scrap yard) amount of cash you'll be liberating by means of the same system you frown upon. My mistake, and my sincerest apology.
Back to the original question, I believe it was answered thoroughly with someone's remark that it was kind of childish. In case that had been open to debate, you put the matter to rest w/ your last post. However, I believe someone else mentioned tuition; which makes for a very strong case in your circumstances...seeing as if Lowe's is where you believe is the best place to spend 2k in lieu of all the problems you so succinctly pointed out...obviously, you've got a lot to learn.
Since you already have a degree, I'd suggest possibly pursuing a PHD. It will school you in conducting research so as you won't sound so childish when only being able to come up w/ the idea of scrapping at Lowe's.
Cheers,
John
