It is a bit of a misunderstanding to say that one can 'pay for someone else'. If you have money beyond subsistence (say in the US anything over 30k-50k/year), you already have a privilege taken from someone else, and certainly all of the vast incomes of the owners are 'paid by someone else' - namely those they control through ownership.
Do you believe that you don't have the right to anything beyond a basic living?
As opebo said, it's a privilege, not a right. A better question would be: do you believe that everyone has the right to a basic living? When an individual earns or accumulates more than the average individual's salary or net worth, imbalance and inequality are created due to the fact there is now less money available in the economy to provide that basic quality of life to the same number of people. Wealth doesn't grow on trees; while it increases nominally, the increase relative to population increases makes it virtually stagnant.
Modern taxation - specifically progressive taxation - exists to make sure money continues to move around in a capitalist economy without being hoarded by those who can afford to hoard it.
So in summary: No, no one has the right to anything beyond a basic/average living because:
a) there is no way to guarantee that economic right
b) for every person given that economic right, there will be at least one person who will have theirs stripped away
