Second of all, the influence of lobbyists on how laws are formed is "well known" as a talking point, and nothing else. There aren't any hard empirical studies that draw a causal line.

In fact, to really drive home that point, I'll reiterate a sentence I wrote in a previous reply to you, but with a minor addition:

Sweden has more billionaires per capita than the US, no wealth tax, and levies broad-based taxes on the middle class. The top marginal tax rate kicks in at 1.5 times the average wage, whereas in the US the top marginal tax rate kicks in at 9.2 times the average wage. Lobbying on policymakers is unregulated (http://www.aalep.eu/lobbying-landscape-sweden). And yet, you might probably define Swedish society as "functional and peaceful".
