I heard recently that there were some Wall Street hedge-fund managers here in the USA that made several billion dollars (each) last year, and only paid 15% tax on their earnings (as opposed to what you and I pay in taxes). But it's not tax policy that I'm talking about, rather the sheer amount of money that these people are making.
If you made $5,000,000,000 last year (I think that was the top amount but I might be cheating the guy out of a billion or two), what would you pay for cables?
Of course if you have that kind of money you are probably going to buy yourself a Midwestern governor or somesuch instead; but if you've just come back from a long day at the office making $13,000,000 (that is $5,000,000,000 divided by 365) by clicking on your computer, hey, what are you going to do, skimp on the speaker cables?
It's hard to spend $13,000,000 a day; you might as well splurge on the cables.
