Wealth varies widely across the 50 states.  The map below demonstrates just how widely.

States colored in dark green have highest gross state product (GSP) per capita; the lowest are in yellow. The size of each State is proportional to Real Gross Domestic Product for 2014. Real GDP is the US grew by 2.2% in 2014, higher than the 1.9% growth in 2013.

Again, state color shows the GDP per person while the state size reflects GDP overall.
