Just a cursory search on Google for the 'heritability of lifetime income' leads me to this from a study in Finland:
> For example, Björklund and Jäntti (2012) estimated using Swedish data that shared environmental and genetic factors explain 40–60% of inequality in a number of productive traits, including cognitive and non-cognitive skills, schooling and long-run earnings.
Assuming that this paper holds up, then at around half of lifetime earnings would be attributable to environment.
Also, speaking purely of heritability factors is a little reductive. Two parents that lack a particular phenotype that, say, is fit for wage growth in our contemporary economy, may have offspring that does. Similarly those fit to succeed in the economy today, may not be in the future if the stressors change.
