in 1900, the federal government was small and did little to intervene - dual federalism, left most domestic issues for state governments to deal with
large change due to the new deal - government became heavily involved in people's lives, introduced government programmes to deal with issues like the great depression
interventionist philosophy continues after WW2 - e.g. GI bill, provided jobs and training to veterans, followed FDR’s example of keynesian economics
LBJ’s ‘war on poverty’ increased the size of the federal government - new departments were opened to deal with a range of societal issues
