Yes, that source is where I live. Here in the European Union that has both a National Health System and Post-secondary Education - both of which are free, gratis and for nothing.
Meaning, easy entry and lo-cost promote the ability of our youth here to obtain the skills necessary for a well-paying job. It also helps them to analyze events lucidly and understand what is happening in both the EU and the rest of the world.
The ability to obtain a post-secondary degree without the barrier of a high-cost has produced this:
What the above shows is that after a disastrous war, Europe was able to catch-up in terms of skills-levels that has allowed the development of a market-economy of the same level as the victor; that is, the US.
And as regards Healthcare, which is also very lo-cost in Europe, money is not diverted from hi-cost Medical Care into the pockets of its purveyors as is the case in privatized medicine in the US, which is a rip-off (given the more than double the cost of EU healthcare).
Cuckoo logic, and asinine. We are better off in Europe for the above basic reasons, even though Americans are "financially richer" on average.
Generating millionaires is not what makes a country
great (except in the eyes of Americans). Assuring that a market economy is fair and equitable - though not equal - is the most honest societal objective of any nation.
It's a shame Americans - fixated on absolute dollar-values ("the higher the better") - don't understand that simple but key concept ...
