Yes and no, I'd say on that. Reagan really worked against unions, I agree. And democrats are always worried about how they are going to get paid. But there was a real turn toward "market solutions" for problems that had traditionally been addressed by government during this period, and I don't believe it was entirely due to corporate bribes or financing. When Bill and Hillary attempted to change healthcare with corporate partners, I think it was more from their genuine belief that that was a new, better way forward. They were wrong, and I am sure that they benefited in terms of contributions, but I think it came as much out of their beliefs about the unpopularity of former democrats and the perception of economic malaise in places like England as it did from union weakness. The democrats could have helped rebuild the unions. They did not (and here I think you are right, because as time went on they really began to be paid well to forget the unions)
