Real income growth is, by definition, after accounting for inflation.

The opposing term is "nominal income growth" which does not account for inflation.

He said 'real' income growth, which I take to mean adjusted for inflation and maybe also various cost of living increases/decreases.

"Real income growth" is the growth in income post inflation.

And even less so if "inflation" has been redefined specifically to be lower, in order to reduce the amount of real money that needs to go into social security.
