It helps to actually read the article before commenting...
Unless I've just read a different article to the rest of you the title just summarises the position that the rest of it undermines. My reading:
1) Some economists put the argument in the title, saying that there is no alternative to spending vast wodges of cash...
2) But they forget monetary policy. QE has given us the room to cut.
3) Which we did in the 1920s when it worked like a charm. That time in wasn't QE but leaving the Gold Standard but the effect was much the same.
4) Meaning that whilst you can still advocate spending more, original argument that there is no alternative is a load of dingo's kidneys.
Hardly the lefty diatribe that some of you seem to think.
