Raising the minimum wage can have a negative effect on jobs, but unless it's hard to find minimum wage jobs right now, I don't see what lowering the minimum wage will achieve. Also there's labor force participation to consider - if unskilled jobs are too low paying, some people at the margins will choose not to participate (for example, by living with their parents).
> Subsidizing the poor increases consumption which is bad not only for the first order effect (throwing away money)... but also for the little thought of second order effect: it incentivizes people to build businesses that cater to consumption that was in the first place unsustainable.

Consumption funded by debt may be bad, but I wouldn't suggest that consumption (in other words, having a consumer-driven economy) is throwing away money. Many goods that people spend their own money on (consumer electronics, cars, clothing, etc) have competitive markets with reasonable prices and/or steady improvements. On the contrary to throwing away money, it seems pretty efficient at delivering utility. Especially when compared to recent trends in healthcare, education, and infrastructure.
I agree with some of the other comments that productivity determines the long-run living standards of a country, and that consumption is not investment and it may be a bad idea to finance it with debt. But I don't think the answer is to reduce people's ability to consume goods & services, but rather to enable doing it in a sustainable way.
