I wouldn't really say wealth inequality is necessarily 'good,' but the various methods of going about it can easily be extremely detrimental to the intended goal and have an opposite effect. Equally dirt floor poor would be even worse than what exists today.

For example, pro small business policies are far more likely to reach the goal as opposed to putting guns to the heads of the ones that have done well.

The net incentive becomes to not start a business and find witty ways to take advantage of the distribution system of that wealth collected by force rather than find witty ways to bring value to the economy as an individual running on his own 'steem.'

The focus should always be on helping the small guy achieve better success rather than focus on taking from the big guy that has already achieved success. Success is the goal rather than something to be ashamed of.
