Spoken word is to be understood by other.If inconsistents speak words which are not owned by theirs,those words can't be understood by social four.Poverty & corruption is in words which are not owned as theirs among social four.

Deceiver(professional) brilliance is that he/she knows he/she is deceiving either professionally or socially BUT NOT AS BOTH.
But inconsistent(brahmana) doesn't know that he/she is not good.
So inconsistent appears as brilliant shouting to be immoral poor.
Hence deceiver business class can be seggregated from inconsistent brahmins.
