The management's rationale for dumbing down the copy was that "Americans are semi-illiterate." That simple. If you Goggle American reading levels, you'll find average national reading levels based on data that include tests of immigrants who do not read English and who speak little of it. The details were not important to these people. It's hard to swallow, but --Hello! --there are a lot of people over here who think we are all fat-assed, lazy, stupid and boring. If there are statistics to support that concept, well...
Regarding this comment from (somewhere) above: "I get SO SICK of people asking me how Bush became President...":
I encountered a fellow recently who commented in astonishment -- fair enough! -- that GWB had, afterall, won the presidency. I found myself blurting out the following:
Fewer than half the people who were registered to vote bothered to cast a vote in that election. Of those, fewer than half voted for GWB. You can hardly say that all Americans elected him--but you can say that a lot of Americans sat it out and let him get elected. I don't think many Brits have heard those figures. It's pretty shocking -- I was shocked myself, rethinking it!
