Rejected petition Working class MPs

In my personal opinion The houses of Parliament (commons ) Have hardly any working class MPs this is a question all political parties need to investigate.The Labour Party have Alan Johnson MP ex post man and Dennis Skinnier MP,ex miner ,it's seems to me and I'm sure the general public will share my personal opinion that to be an MP these days you need to be career politician university educated a ex doctor,Barrister or In David Cameron case had a privilege Eton education.How can these MPs represent us when can possibly show empathy to government policy like the bedroom Tax.I think that parliament is slowing moving forward with more Woman MPs .But there's need to be Questions answered on Working Class MPs before it's too late.
