毕竟，在真正的金矿被发现之前，卖铲子的依然会赚钱——只是不再享有过去那种非理性的“信仰溢价”而已；而随着金矿逐步显现，能实现商业化落地的下游企业，才能将成为未来的核心增长点。
Southwest Airlines stays pumping out discounts for its travelers. Its Spring Forward Sale is live from March 9 through March 12 and you can book a one-way ticket for as low as just $49. There is some fine print as always, so listen up. The discounted flight prices are valid on travel between March 31 and June 10 in the continental U.S. and inter-island Hawaii only, and a 21-day advance purchase is required. Restrictions, exclusions, and blackout dates apply. After some poking around, I was able to find $69 flights from Nashville to New York City, $67 flights to Atlanta, and $49 flights to Columbus. I suggest heading to the sale page and selecting your departure city from the drop down list to get an overview of costs.
