Again, what good does that do when the people lower down have no money to spend because their tax burden is too high?
Starting or expanding business enterprises is, of course, likely to result in increased employment. This could provide additional money to:
1) persons who are unemployed (and thus, probably are not lacking money because of their tax burden)
2) persons who are employed (and have a tax burden) by the specified enterprise, by means of a raise in salary
3) persons who were employed elsewhere, by means of a better employment opportunity, now at the specified enterprise
Furthermore, all three situations could be produced indirectly, such that the new or expanded enterprise, generates a product or service that beneficially affects, or causes the creation of, other enterprises generating related products or services.
Also the new or expanded enterprise may produce innovations that result in lower prices (this would, of course, have no effect upon persons with
no money to spend, but it could affect persons who did not have sufficient money, before the lower prices occurred).
Rich people only spend money for two reasons, for pleasure, or to make more money.
I suppose that would depend upon what is defined as "rich." I tend to think that people, generally, have similar reasons to spend money; the extent to which they spend particular amounts of money, for particular things, depends upon their circumstances, which can be complex and changeable.
the question is whose tax burden to lower. Obviously you subscribe to the Ronnie the messiah supply side theory that the wealthy will let it trickle down if you reduce their burden.
I don't suppose that "the wealthy let it trickle down." I do recognize that a
greater ability to produce economic activity, by those who are in a position to produce economic activity, will tend to produce a
greater amount of economic activity, and that a greater amount of economic activity tends to be widely beneficial, resulting in more employment, more innovation, and more opportunities of various kinds.
Whatever purpose a tax cut for someone who sends a job overseas is, it certainly does not benefit anyone who draws a paycheck and pays taxes, including me.
That is not a reliable supposition, since economic activities that occur abroad, can have domestic effects. Note, for one example, the Wright Brothers' enterprise; its beneficial effects are worldwide.
Anyway, I don't know that anybody actually gets a tax cut for sending jobs overseas. However, it does seem likely that low business taxes would tend to minimize the likelihood of jobs' being sent overseas.
