What a dumb thing to say ... if a business has more capital at its disposal and decides to expand ... new workers WILL appear ... and its not magic ...
... nor will it improve the skills of those already here.
Has this guy ever owned a business? ... A business that trains the right employees to do their job better ... or trains them to do a higher value job ... and you improve the skills of those already there ...
The increase in capital due to the reduction in corporate tax rates will directly affect what this knucklehead says it wont.
And what will drive the decision to expand? More money from tax cuts? Or increased demand for their product? The first does not automatically lead to the second.
