The political overtones would be far greater than that. It's never really commented upon, but Mass Effect unambiguously presents free market capitalism as the social science equivalent of the wheel. Not only is it the economic system that Citadel Space uses to ensure a good standard of living, but the fact is that nearly every single galactic civilization practices free market capitalism by default (the batarians and kett are the only real exceptions who exist in notable numbers). That's a pretty strong statement on its own, and it also applies to other sci-fi works that do this.
It is basically in-universe confirmation that capitalism is the scientifically ideal economic system, so ideal that dozens of different species with nothing in common came to it independently. The various species of Mass Effect are quite distinct from each other in their governments, religions, social structures, cultural institutions, and so on, but free market capitalism (albeit in different strains, e.g. it seems likely the turians are utilizing Chinese-style authoritarian capitalism and the asari a more decentralized variant of European-style liberal capitalism) marked by private property, private ownership of production (even turian weapon manufacturers and mining companies are privately-owned), private capital accumulation, market-determined prices with minimal to no controls, and wage labor is ubiquitous to all of them. Every advanced civilization will inevitably utilize it.
These days the audience just takes that as a given. But in the 60s and 70s it would be taken as a statement. Especially since, unlike e.g. Star Trek which bypasses the question of economics at every opportunity, ME's lean is impossible to ignore. All technological advancement we see is made by a private firm. Every hub we get to walk around is teeming with (predominantly service-based) businesses both large and small, and advertisements for them, from weapon manufacturers to pharmaceutical companies to clothing stores to video game developers.
There are seemingly no restrictions on the movement of people, information, or goods within Citadel Space. There are multiple references to buying things at fair market value, obviously indicating prices are determined by markets instead of central planning, even in the authoritarian Hierarchy. There is a galactic scale unified floating currency and central bank. Colonial development is overseen by governments but is spearheaded by private corporations. So on and so forth. Even the one major faction you'd expect to have an authoritarian command economy, the turians, are specifically noted to only be a viable power because they let the Ferengi-esque volus run much of their finances.
Speaking of which, it's specifically noted that the volus have a massive economy out of proportion with their population because they're such effective industrialists, merchants, and entrepreneurs, hence they thrive in the hyper-capitalist Citadel Space. Citadel Space is a liberal capitalist's paradise.
