Also, whilst Keynes had a number of policy preferences which are unfashionable now ('euthanasia of the rentier' through sustained low interest rates being one), the General Theory explicitly was about how governments could soften economic contractions like the one we're experiencing now, and explicitly wasn't about governments running structural deficits. At various times he argued that higher taxes were necessary and desirable if the government wanted to use more resources, and that government funded services were more desirable than widespread redistribution payments.
