For this reason, I wonder if near-zero interest rates and corporate bond purchasing will ever end in the US. If it continues, isn't it kind of like the government supporting these large US corporations in the similar way? Encouraging them to take any contract or spend on any investment that returns more than 0% in interest? I'm not saying this would be "good" or "bad". I imagine it would be bad for smaller companies, but good for larger ones, maybe good for American competitiveness in world commerce (for a while) but could be bad in the long run because we'd be committing to a race-to-the-bottom price war with a competitor who has a lower bottom price than we do.
