I would like to take up one of Moniques ideas:
„Stop the taxation flight by corporations: these taxes could pay for lots of projects and will create jobs afterwards.”
Therefore, I would like to reference the theory of Arthur B. Laffer (a supply sider): He said, that in order to receive a higher revenue - the government have to reduce the tax rate. (Please see my chart attached)
This is one way for governments to obtain more taxes - but it is important to spend this additional income reasonable in future investments!
