US has regressed to developing nation status, MIT economist warns

The economist describes a two-track economy with on the one hand 20 per cent of the population that is educated and enjoys good jobs and supportive social networks.

On the other hand, the remaining 80 per cent, he said, are part of the US’ low-wage sector, where the world of possibility has shrunk and people are burdened with debts and anxious about job security.

Mr Temin used a model, which was created by Nobel Prize winner Arthur Lewis and designed to understand developing nations, to describe how far inequalities have progressed in the US.

When applied to the US, Mr Temin said that “the Lewis model actually works”.
