I've written on these themes before...

but PJTV does a good job summarizing them here. 

1. Since investors and the market in general hate uncertainty, have a vast array of conflicting ad hoc policy decisions so as to create uncertainty everywhere.

2. Transfer money from those who create sustainable jobs to those who create unsustainable jobs, e.g., the government

3. Promise to invest money in things that will enhance the country’s infrastructure, such as roads and internet access, but then practice bait and switch on a breathtaking scale, so the effort is swamped with pork for pet projects dear to Democrats
