Many differences between the US and EU, not just workers benefits. IMO, more likely to affect startup company success in becoming big: - One common language, one culture, one currency across the US (sure, differences between states in culture but not as diverse as in Europe). This is gradually converging via the EU, but the US has a couple of centuries headstart... - VC funding concentration in California (think about how many of those "US" companies are from California); VC investors in US are global names if you work in the industry, in EU they are regional names. - Generalising a bit here, but from my experience, I find work/life balance generally considered more important in EU compared to US. In the US, work is given a higher priority and if your boss asks you to stay late/work on a weekend, many colleagues in the US would do it, European colleagues would put e.g. family first instead. - Side note; work/life balance point can be reflected in terms of national culture, e.g. "The American Dream"
