Blaming the last government for not taking action on Payday loan companies seems a little rich. The payday loan industry, typified by companies like Wonga, is a recent phenomenon. Wonga was not even started until around 2006.
And it takes time - several years, usually - for the effect of the practices to manifest, to collect and review the evidence,etc. I do not lay the blame for action on anyone, politically speaking - but some action to better regulate the industry is plainly required, especially the interest rates they can charge and the processes by which people can access loans from several different payday loan companies at the same time.
And the impetus for change has come from Labour. The Tories /this coalition have been resistant to taking action on the payday loan companies until very recently.
