Do not mistake economic indicators such as GDP or "growth" for meaningful measures of economic health.
It is an indicator and it's not totally non-meaningful. But GDP growth, when it's at the price of increasing the public debt and inflation, is no real growth. Instead of looking at the US, let's look at what used to be a relevant ally... In the eurozone, for example, politicians are hiding the lack of growth behind a growing mountain of public debt and the GDP growth ain't even beating inflation since the 2008 crisis…
In any case where the European union keeps failing is that it keeps not focusing on creating as many common rules and regulations across the EU, so, yet again, scaling your french business beyond your borders, or bulgarian one, is always very difficult.
Most countries in Europe are ridden by pointless nationalism on so many matters when our biggest issue is creating a strong internal market in Europe, but our biggest economies are still manufacturing and exporting ones, with little focus on the strengthening of our internal markets.
