Governments don’t have money: They can only create jobs by taking job-creating money out of the another part of the economy. Government “job creation programs” destroy jobs on net, they don’t create them.

Governments can’t predict the future: They have zero knowledge about what technologies will work, will find a willing market, and will create jobs.

Governments suck at picking winning technologies: With no market restraints on reckless gambling, planners simply pick whatever technology that they happen to love, and bet taxpayer money on spreading it. Sure, every so often, the planner gets lucky, but more often, they make bad bets and simply hide the losses and the negative side-effects.
