It's not just about "jobs" it's about opportunity costs. If tons of money is invested in marginal businesses that don't pan out, then we end up with a zombie economy that is busy performing useless labor/services and we end up stuck like Japan has been for the past decade or more. If the same money is invested in good ideas that pay off, we end up with everyone being better both financially and we have better tech and services. Part of the reason why these marginal businesses can get along is because borrowing has been cheap and there has been a shortage of good ideas to invest in, so it's a catch-22.
