As of June 8, 2023:
Nominal exchange ≠ real cost. Germany generally has higher VAT (19%), higher energy, higher regulated prices (health, education, transport subsidized). US has lower taxes, higher healthcare/housing/education out-of-pocket. PPP (Purchasing Power Parity) ~0.85 EUR/USD — meaning €1 in Germany buys roughly what $0.85 buys in US for local goods/services.
