You have NO idea what you're talking about and don't understand this whole topic. Pity that...............
Not quite the same scale of "scam" as the brokerage houses / banks. Below is a small comparison of the operating margins of various entities (a measure of how much you are being over-charged for services provided):
WALLSTREET TYPES
JP Morgan - 39.17%
Goldman Sachs - 33.07%
Merril Lynch - 30.83%
GROCERS
Krogers - 3.18%
Albertsons - 3.08%
Safeway - 3.52%
Not quite on the same scale are they?
How about BIG BOX STORES
Home Depot - 11.53%
Walmart - 5.88%
Target - 8.11%
MANUFACTURING?
Caterpillar - 9.8%
Boeing - 3.15%
Deere - 9.8%
"EVIL" BIG OIL must be bigger right?
Exxon Mobil - 15.38%
BP - 9.15%
SOFTWARE GIANTS
Microsoft - 42.19% (hey we found one!)
Keep in mind that these margins probably already deduct the cost of "bonuses" as they are construed as operating costs.
