I would say upper middle class joe has is better in the states. Everyone else is barely clinging on to their lives in perpetual serfdom because of no universal healthcare, extreme housing costs, extremely expensive education, etc…
Statistics about average and median income in the US and EU is widely available. Also the graph linked above about disposable income shows that only in the lowest 10th percentile people in Europe are (marginally) richer that in the US. Starting with lower middle class the gap becomes quite significant already, and what's important is only growing.
