问一个句子，不大看得懂，请大家帮我分析分析，谢谢啦！

（1）Hagen（人名） uses two personality types: the authoritarian and the innovative, and the conclusion is that the number of innovative personalities in a society is decisive for its economic growth.（2）Hagen also explores how social exclusion and degradation produce individuals determined to accumulate wealth. （3）He argues that people who have grown up in certain minorites develop a much stronger psychological propensity for entrepreneurship than those who have not.

第1句是上下文，说Hagen把个人特质分为权威人格和创新人格两种，社会中创新人格的数量对经济发展有决定作用。

关键是第2句，这里面的句子结构我看不懂。social exclusion好像是社会排斥，degradation是社会退后。

第3句里面的minorities难道是指少数民族吗？不太像，国外的理解好像跟咱不太一样。
