I do have a property manager in place, however, I want another pair of eyes.   

Even though she saw how hyped I was, she's the type that is content just renting, working full time, putting money in a savings account rather than paying off interest accruing debt etc; now pair that with the bad taste in her mouth from our prior real estate venture and you've got a wall of "No's!"

In one, I make all the decisions, in the other, I have to hope China doesn't reposition their currency.

Try reading this book by John Bogle:Enough.You clearly have more than enough money to do a blend of passive index investing and summarily discard the notion that you need to spend any additional effort for the rest of you or your family's life on anything as banal as the pursuit of additional pieces of currency that add no real value to your life.

I won't give my input on your remarks on "who's fault" anything is as there are many threads debating that exact topic.Where can I buy a pair of those eyeglasses?

Just a few options you have to invest in are: residential and commercial real estate, undeveloped or raw land, real estate notes (mortgages and deeds of trusts), private limited partnerships (limited liability companies and C corporations), tax lien certificates, foreign currencies, and oil and gas investments to name a few.

Hard work + a nearly supernatural level of dedication and focus + a huge pair = a billionaire

If you have the tool all you will need to do is put it in the right  pair of hands.

I manage a pair of 1930s boarding houses and they are definitely a labor of love.
