The article contrasts the operating environment of “Big Three” auto-manufacturers across countries. It compares manufacture costs in Germany and Japan with those in the US, and the paragraph you cite links through to a (2004) article in which it is estimated that pensions and health insurance combined add $1,784 to the cost of a car in the US.
You need to subtract some contradictory numbers in the article to come to a number you can ascribe to health insurance, but somewhere between $400 and $800 fits a quoted “$900 will flow to [pension] funds”.
Given this context it is reasonable to argue that General Motors is (or at least was in 2004) at a competitive disadvantage to manufacturers in Japan or Germany as a result of the US having no universal healthcare system.
Lamentably for your position, just because there are political decisions involved that bring about consequences, factual discussion of those consequences is not itself necessarily political.
