一个英语翻译问题，请教各位大神帮帮指点下感谢啊！！！！

And few things define what it is to be middle class in America more than owning your own cornerstone of the America Dream:a home
关于这句的翻译有人译成：如何定义中产阶级，再也没有比成就美国梦基础更重要的事物了这就是房子
但我怎么也看不懂这句译文，more than这里什么用法？后面接的那个怎么翻译？前面那句还好理解

回答你的问题之前，先给你看个句子：

Few people like BBQ more than I do. 也可以省略do，即Few people like BBQ more than I.

意思很明白，很少有人比我更喜欢烧烤了。

其实原句是：Few people like BBQ more than I like BBQ.

more than这里是在比较，比较的双方是：

few things 和 2. owning your own cornerstone of the America Dream:a home

两个互相比较的结构是：

Few things define what it is to be middle class in America.

Owning your own cornerstone of the America Dream, a home, defines what it is to be middle class in America.

原句就是：Few things define what it is to be middle class in America more than owning your own cornerstone of the America Dream, a home, defines what it is to be middle class in America.

省略重复的宾语部分what it is to be middle class in America，defines变为does免重复，句子即为：

Few things define what it is to be middle class in America more than owning your own cornerstone of the America Dream, a home, does.

最后的does往往也可省略，即有了你的句子：

And few things define what it is to be middle class in America more than owning your own cornerstone of the America Dream:a home

你没给出译句解释啊，说实话还是看不懂

房子——实现美国梦的基础，没有什么能比这更准确地定义美国中产阶级了。
