It is perhaps unsurprising that shadow chancellor John McDonnell has returned at this conference to a signature market interventionist policy.
Indeed he wants to be so associated with a new cap on excessive interest payments on credit card debt that he has even suggested calling the policy the “McDonnell amendment”.
Credit card customers in persistent debt are estimated to have paid about £2.50 in interest and charges for every £1 borrowed.
Labour says it will cap this at £1 or 100% of the borrowed amount. Three million Britons are in this unpleasant situation, says Labour.
Both main parties now believe in different ways and with different methods that the state should have a stronger hand in directing outcomes of private markets.
Indeed, the PM has made a point of echoing some of these Milibandite policies from the Living Wage, energy caps, crackdowns on executive pay and some rental fees.
So, Mr McDonnell has simply extended the scope of the interventions he says he can make to correct an unfair outcome.
Announcing an intervention like this is the easy bit however. Making them work is another matter.
The fear would be that credit is simply rationed even more for those perceived as high risk, or the costs loaded on elsewhere.
The bigger political play here, however, is Labour trying to eat into the Conservatives’ reputation for economic competence with predictions of a debt-filled recession to come.
Labour has not won in three general elections since the Great Recession, and the Conservatives are only too keen to remind the public what happened on Labour’s watch a decade ago.
But the recent run-up of personal debt on credit cards and car loans has happened on the Conservatives’ watch.
As interest rates start to rise again, and Brexit uncertainty endures, Labour sees an opportunity to get on the right side of the economic numbers for the first time since the financial crisis happened on its watch.
This anticipation of financial turmoil to come also explains the inexorable repositioning of left-wing eurosceptics such as the shadow chancellor on Brexit.
