We tend not to pay much attention to what luvvies decide to worry about in their own time. They are, after all, hired to read out the words of others rather than think for themselves. However, we are right behind Michael Sheen in his concerns here. Not in what he's actually concerned about, but in the method he's decided to use to express said concern: 

Michael Sheen has decided to scale back his acting career to devote himself to campaigning against high-interest credit providers, like Wonga and BrightHouse, and working to find fairer alternative sources of credit.

He will begin his new undertaking on Tuesday in Glasgow, where he will launch the End High Cost Credit Alliance, a campaign group of politicians, charities and tech companies he has brought together, working to promote more affordable ways of borrowing money. His dedication to tackling problem debt has been inspired by witnessing difficulties faced by friends in the Welsh town of Port Talbot where he grew up, a region struggling with the decline of the local steel industry.

As indicated, we don't share the worry. But we do like the method:

....he decided to focus on promoting more ethical and cheaper alternative providers of instant credit.

These exist already, but lack the investment that companies like Wonga have, so aren’t advertising on daytime television and Facebook, and are not widely known. His campaign group’s manifesto promises: “We will back fair finance providers, equipping them with the resources to compete and win against high-cost credit providers.”

He's putting his money where his mouth is, always something to be applauded. But more than that, he's going out there to explore the market options of providing what people desire - that access to cash in times of trouble - in a more efficient and thus lower cost manner. Ain't that great? 

Changing the world in your desired direction through market competition. We approve, thoroughly.
