This book is primarily about good people clashing over the advantages and disadvantages of multinationalism verses mainstream America based on the Melting Pot. With Russia stealthily urging American minority groups to remain separate and maximize differences with mainstream America, resolving the clash becomes important and immediate. It brings to mind Abraham Lincoln's warning that "a divided house cannot stand" when he faced the clash between slavery and non-slavery.For readers to fully understand the present clash, this book can be viewed as a primer on relevant American history from the time it became a nation of immigrants. That will also help readers to understand why Congress cannot agree on present day immigration policy.And now America faces still another clash brought about by America's extraordinary success that created a huge economic inequality between the haves and have nots. Serious issues as to socialism, communism and capitalism have arisen. Some Americans are now proposing a form of communism for America, an awkward reversal from capitalistic America having previously condemned "godless" communism. China and Russia had dumped communism only to adopt capitalism. This too can divide our house.
