It is important to note that there are many factors to consider when making broad statement like defining the American Dream. To me it is having choices. Renting is a sound strategy sometimes and sometimes it is not. There are way too many variables to consider. I could argue both cases very easily depending on ones' specific situation.
An interesting stat is that 25% of resident were moving out to buy a home and now only 12% do. Sounds familiar? When it was a bad time to do more people made the jump into home ownership and now that the market appears to offer great opportunities less people make the change.
There is a shift in our economy with some short term and long term impacts. I do believe that the home ownership is a good move if it makes sense. Just plain old common sense...
