If the mass of employers has more money to spend, they automatically create more jobs because they spend it. This is a no-brainer. They are the relevant part of every country out there and the whole system. This is why companies like Walmart are so huge. Many people spending small amounts of money generating huge revenue.

Your rich investor who gains a little bit more due to tax evasion of the company they invested in gives you nothing most of the time because they just reinvest it elsewhere and even if he buys one more yacht with it, they are so few, that their impact on the job market is negligible.

Now the fact that the company which does not pay the taxes for the infrastructure they freely use to generate their revenue can go to a politician and tell him: "give me taxpayer money/let me pay less tax or I go to the county next door" does not have anything to do with employment. It's a hole in national law. If there would be no politician who's allowed to throw money at those already wealthy companies, they would have null leverage, the subsidies would go to those who really need it, the companies would have to pay their taxes (you can't outsource everything) and the mass of citizens would profit from more money in their pocket, a properly maintained infrastructure and money the state has in emergencies like we're witnessing today.

Your "single dimension" view on the situation is the old prayer those who steal taxpayer money/not pay for what they use have told us for years. It's a ridiculously shitty story nobody buys, so please get a dimension.
