When personal income taxes for the wealthy are low, there is a strong incentive for business owners and executives to take money out of the business for themselves.
When taxes on the wealthy are high, there is more incentive to keep that money in the business and reinvest it, allowing the business to grow and create more jobs.
Raising taxes on the wealthy, in and of itself, creates jobs.
Putting that money toward social programs to help the poor (who will then have more to spend) creates demand for goods and services, which also creates jobs.
No one has ever hired a worker because they had extra money lying around. They hire because they need to meet rising demand for their product or service.
