Is that an Echo I hear?

I just read that the USA Millennials (ages 18-34) in 2015 surpassed the number of Baby Boomers (ages 51- 69) living by 500K (Pew Research estimates 75.4 million).

You might ask how this can be if only 66 million Millennials were born in the USA?  Now you see the power of the immigration issue (almost 9 million immigrants ages 18-34 which is nearly 12%).  

So what?   Let me postulate by topical area:

Immigration:  Amnesty, Acceleration, and Accomodation
Politics:  Common ideologies in this group will frame the future social programs.
Consumption:  Lots of houses, and furniture to be purchased (Harry Dent's book relives)
Culture:  More diverse and less emphasis on minority differences.
Religion:  More divisive views about role of religion (see: Millennials views)
Financial:  More Debt, Inflation, and higher Interest Rates
Technology: Increased dependency on "intelligent assistants"
Family:  More babies crying :) on planes

And the Bottom Line:   Twenty years of echo in the making.
