Personally, I think we need much tighter regulation. There was a study at some point that found that lobyying has a yield of 22,000% in the US, which is a wild figure (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1375082). Lobbying very seriously undermines democracy. The US system of calling lobbying via donations as free speech seems ludicrous. France, for instance, has much tighter laws on lobbying.
