Speaking to The Hollywood Reporter about his new film The Angels' Share, Loach said that one of his priorities is to "describe and celebrate" the working classes.
"It is central to my filmmaking philosophy," he confirmed.
"Generally speaking [the working classes] are presented in a 2D, stereotypical way so they can be glossed over in films. So it is always my intention to describe and celebrate them in a different way."
Loach continued: "Our aim is to put them central stage, and explore their contradictions, hopes, humour and lives without patronising anyone.
"The overriding point of it all for me is that any change [to society] will come from the working classes, and no-one else, because everyone else is striving to look after the status quo and protect themselves."

Asked whether comedy-drama The Angels' Share could be described as a more optimistic film than his 2010 Palme d'Or contender Route Irish, Loach agreed that it could.
"Route Irish... is a very harsh film with a tough ending for audiences," he mused, "and I think we felt we wanted to do something with a bit of a smile for people at the end of it.
"Of course the world doesn't change, and it's a bleak place for the people we are describing and portraying, but they themselves deal with it with humour and compassion and show a resolution to get through the hard times."
Loach's long-time producing partner Rebecca O'Brien hit out at the BBFC this week for demanding that cuts be made to The Angels' Share in order to avoid an 18 certificate.
