For instance,if someone is able to create wealth without creating more value, and it must be at the expense of another source.
It’s been assum as a zero-sum game and has negative effects to economy,that’s absolutely a bad ideology.
You don't judge a man's inability to acquiring wealth through the method you dim ideal to mean that his wealth is of no worth. Not everyone will be able to build his wealth in alignment with what stands to help the general economy, in our era, what matters most is that you are able to make yourself financially bouyant enough to meet all your needs, if it does not translate to helping the society at the initial view doesn't mean your wealth is useless.
It is not a must that because you're wealthy you're supposed to add value to the society, the government and special agencies that have been assigned such role are the ones that are primarily obligated to create real values with the wealth that could be best looker at as that of the society. If I'm wealth and you're poor, it's not your right to feel that I must use my wealth to take you out of your poverty, it's your duty to work yourself off that state and not depend on me to take you out of that state. The way one chooses to make use of his wealth differs.
