I wonder who wrote the USA Inc article, sounds very alarmist, very Tea party-ish!!
Anyways the reason im bullish on the US is these guys came to the brink of financial armageddon in 08 and they rushed in to put checks and balances that ensured that they woudnt be in the same position again. US Corporations are sitting on huge sums of cash, they basically adopted a lean model and the feds instituted stress tests that they have to abide by. I was at the mall over the weekend and you could hardly walk coz there were so many people. I know the first reaction is Americans buy on credit, but that credit has a limit. Despite an economic downturn, the fact that people are shopping to me is an indicator that the economy is picking up. I remember in 08 the malls were empty.

Basically they are prepared for the worst. But this is not to say that African stocks will not outperform US, I think the wise thing to do is diversify on both markets and hopefully buy when there is blood, if the Depression ever comes around.
