I dont know what the big deal is with a million credits. I view it like most people dont understand it because they play games the have multiple money currencies. (ie platinum/gold/silver/copper) If it were in say WoW, a million credits would only be roughly 100 gold.
100 gold = 10,000 silver = 1,000,000 copper
So really, all the zero's simply make it look more impressive than it really is.
Heck, even in real currency, I only equate the credit to a penny in USD, which would make it seem around $10,000 USD.
