"They are usually math experts and they say math can predict the future so, if that’s true, why didn’t they see this coming?"
Most of the finance people who didn't see this coming were either simply bad at math, or distorted the math so heavily to fit their preconceived notions of what the world was like that it no longer made any sense. The people who do know the most math- Renaissance Technologies, led by former math professor Jim Simons- were up 80% during 2008 (http://seekingalpha.com/article/138283-barron-s-top-100-rank...).
"Also, income inequality, measured by the ratio of the top 10% of wage earners compared to the bottom 90%, increased dramatically during both presidential terms. The ratio increased from 7.1% in 1928 to 7.8% in 1932 under Hoover, and from 6.8% in 2001 to an outrageous 7.9% in 2006 under Bush, the year the Center For American Progress study was conducted."
I presume what he means here is that the richest 10% now have an average income which is 7.9 times higher than that of the bottom 90%; using "percent" in this context makes no sense at all.
"Further, Both Bush and Hoover took steps to either deport and/or restrict Mexicans from immigrating to America, which is a key signal I will discuss in detail."
Wait... what? I don't know enough about Hoover to say, but there hasn't been any significant change in US immigration policy under Bush, and in any case, Mexican immigrants are a small percentage of the American economy (maybe 5%?).
"Finally, both Bush and Hoover took steps to inhibit certain forms of new energy – Hoover passed prohibition, which eliminated ethanol, and Bush refused to pass any bills that promoted renewable energy."
Prohibition was passed during 1919, a full nine years before Hoover became president; at the time, Hoover was preoccupied with keeping the Russians from starving after the Bolshevik revolution.
"Some examples of things that can’t be easily counted that can indicate that a major recession or depression is looming are lawsuits filed by established companies that seek to block competition or progress (RIAA, AP)"
Companies have always done that, during good times and bad, dating back to Standard Oil and their monopoly over the refining business.
"U.S. citizens complaining about Mexican immigrants taking their jobs, "
Again, US citizens have always done that; see http://www.sfgate.com/cgi-bin/article.cgi?file=/gate/archive... for a humorous take on this.
"In the US, every 40 to 80 years a Civic Generation (or “Joshua Generation”) appears that looks to re-energize social, political, and government institutions to solve neglected national issues, usually by dramatically expanding government."
This is a very far-reaching claim with absolutely no evidence.
"As a result, when we have an election with a large, deep, and stressing fracture between the two parties, you will see a pause or decline in business and the stock market, as people wait to see if the country is taking a step toward progress, or a step back toward the Idealist status quo."
The previous presidential election (2004) was extremely divisive, yet the stock market and business went up for the next three years.
"With all pre-Boomers retired, corporations lost a lot of supervisors, managers, and directors, or those in power positions."
Generations don't work like that; they're continuous, not discrete. There's no large group of people who all retire at the same time; the generation before the Baby Boomers was unusually small (http://www.seanet.com/~jimxc/Politics/Pictures/Fertility1.jp...), so if anything it should be the opposite.
"When combined with Generation X, they will own 70%+ of the workforce, so their 70% take of the available income, which drives the economy, will dictate what products, brands, businesses, and industries will be viable."
The Baby Boomers do a disproportionate amount of spending in this country, and are heavily entrenched into the power structure by virtue of their large numbers; see http://www.telegraph.co.uk/finance/personalfinance/2919408/B... and http://www.nuwireinvestor.com/blogs/commoncensus/2008/03/ame....
