Ok but does this take into account which industries are monopolistic or oligarchic?

In an industry with real competition you have tight margins and can't afford to spend money lobbying.

In an industry with a monopoly, you have huge margins can reduce the economic surplus of everyone else down to close to zero (often deep into the negative if you count for externalities, looking at you oil and gas), so they are strongly incentivized to fix your market and you can't afford not to lobby...
