Love the title. A very true statement.
My Australian friend who has been living and investing in the US for the last year has been very disappointed with that aspect of American culture. In Australia, true relationship and loyalty in business is most important. In the US, he's found that people just take what they can get from the relationship, then move on.
Hey, you should write your own book some day :)
Funny you mentioned that - I have a book on real estate investing that can be found at ScaredycatGuide BookStore or on Amazon Kindle: Investing in Rental Properties
And yeah your friends sentiment is why I love Australia and was so close to staying there for good instead of coming back to the States back when I visited for a couple months.
