I fear you might be mostly right about global political outcomes favored by big capital. However, both example countries you cited have much stronger social safety nets than the United States. The research shows there is a spectrum, but that multi-party systems generally do create greater citizen representation.

Martin Gilens and Benjamin page published an article that uses data to come to this conclusion about the public's influence on American policy:

"The central point that emerges from our research is that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while mass-based interest groups and average citizens have little or no independent influence."

Iskander De Bruycker and Marcel Hanegraaff authored a recent study, focusing on the EU, in which they "demonstrate that interest groups with more economic resources are generally more influential, but only if their policy positions are congruent with a public majority." Sorry this one is paywalled. Such is the state of academic publishing. :(
