My city just received 10 hybrid buses from the “stimulus money”. They cost $540,000 apiece. This is a city with ELECTRIC buses. Who’s paying for them? Your city? My state got millions of dollars of “stimulus money” to build a hi-speed rail that will not have enough service to pay for itself. Who’s going to pay for it? Your state? If every city, town and state got a piece of this package who is left to pay for it? It’s borrowed money.
