Corporations may touch a large number of people but those people are not a representative sample. Further, corporations are not lobbying for the interests of that large group of people, they are lobbying for the interests of the corporation, whose interests may incidentally and temporarily align with the groups you mentioned. The interests of the corporation only align with those of the people you mention insofar as those are in line with maximizing profits. However, this completely ignores the externalities of maximizing profits, such as those to the environment. More broadly, a country whose politicians represent the interests of corporations is no longer a democracy. Democracy is for people. Corporations are not people. They are abstract legal entities wired to maximize profits. The fact that they are composed of people is immaterial, since they do many things contrary to the interests of those people all the time.
