Compared to Germans, Americans save very little. In fact, the personal savings rate in the US is in the single digits.

At the end of last year, the rate stood at just 5.5% according to Federal Reserve data, Americans save about 1/3rd of the savings than Germans. In the US, the savings rate was nearly half the current rate before the global financial crisis of 2008-09.
As a socialist country Germany offers many benefits such as free healthcare for all, free college, pension, etc. to its citizens, So Germans could spend more and save less. But due to cultural reasons, Germans are traditionally risk-averse and debt is considered as a negative or a bad thing to have. Hence Germans tend to save more and pay with cash for purchases as opposed to using credit cards or take on home loans.
Americans on the other hand get limited benefits from the state and fund themselves for much of the needs such as education, healthcare, retirement, etc. So it may seem prudent for Americans to save more for the future. But due to cultural and other factors, Americans save less as evidenced by the very low savings rate and consume more goods and services, Much of the economy in the US is driven by credit and taking on debt is almost considered as a right rather than a bad thing or a privilege Other factors such as heavy marketing at all levels by companies encourages people to spend than save.
