The system has been designed like that by mother nature and what government does is to enhance the rich gets richer chain flow. 
Who is to blame? 
The best way out is to join the league. Get rich or die trying, since we can't beat them, we better join them.

Sad but true ... As for answers, well, they are myriad .. but ultimately they are all flawed because human beings tend to be greedy.
Design something for the masses and there will always be one person looking at how they can hack it to make themselves wealthy! 
Any solution has to be designed to address that very human failing.
If you don't engineer equality, then you can guarantee that you won't get it, irrespective of the intentions of individuals or the system adopted.
As your infographic clearly illustrates, it only takes a small and greedy minority to screw things up for an overwhelming majority.

Sociopathic tendencies breeding together for many centuries produces ultra sociopaths incapable of seeing the big picture. Their genes have been selected to hoard at all costs

It's just because God is stuck in sky traffic...but when "he" gets here...

Its like poor are getting poorer and rich richer....

By design and they want more....and they wonder why people want “out” with cryptos

The wealth inequalities are horrible. Although I like the basic idea behind communism and socialism, history has shown that capitalism is the most efficient system we had invented and tested so far.

Decentralized monetary system or revert to gold and silver is probably the best solution. 
Thanks for your post.

Not sure about giving socialism and communism an equal billing with capitalism, there. This inequity is 21st century neoliberalism in action, and capitalism is the significant player there.

If you want to redistribute wealth (I do!), then it is left wing thinking that needs to be applied.

If it is about money ...i guess everyone is eligible to read this

This is what I will called socio-political and capitalist injustice. In a society where the rich are getting richer and the poor are getting poorer, there is a need for a drastic and revolutionary change in the way things are been done and run in our present day world.

with the way things are going we may get to a stage where there will be revolutions. Except an equitable way of distributing wealth and resources is been implemented soonest. Nice and helpful post @cortexx

Well, there has historically been no system that distributes the wealth downward. The phenomenon that redistributes the wealth, for good or bad, is when the system gets upended (wars and revolutions, etc). The flaw in this is that the former have-nots do not actually seek equal distribution (at least not for more than a generation or so) but seek to set themselves up as the new haves.
Add to this the fact that the only entities currently able to upend the world's system will not have much popular support because they have made this intention obvious and have made themselves more abhorrent in the eyes of the have-nots than the global haves are.
Communism attempts to enact fairness by banning greed. The problem is all it takes to poison the system is for one person with a position of power (power which no one dares question because it allegedly comes from the people, hence the term "Dictatorship of the Proletariat") to get greedy and it becomes indistinguishable from fascism. Take for instance the USSR or the PRC.
Capitalism has less admirable rhetoric. It acknowledges greed is a Human motivator and then says "well, since we can't get rid of greed, we should at least try to get something useful out of it," and creates a system where greed is best served through innovation.
Neither of these is golden but so far Capitalism has narrowed this gap to the (comparatively) narrow gap it is today. If you find that statement odd, look at what a similar chart would have looked like under the old Feudal systems where the top cats quite literally owned everything up to and including the country.
Something more advanced than Capitalism will come along eventually (Human history is one of mostly progress after all), but Socialism and Communism simply aren't it. As to the question "okay, what is it," well I don't know. It hasn't been invented yet.

Wealth inequality is natural to any market system. It won't go away if the core mechanics of how our society functions stays the same. We have all the knowledge and resources we need to create a shared abundance without damaging ecosystems, yet we have a monetary system that encourages dirty practices to save costs. Money is the root of all evil, most have heard that phrase, yet few seem to be able to step back and ask themselves if we need to have money. We don't.

not sure how accurate the figures are but the premise is 100% correct, it is massively lob sided rich are getting richer poor are getting poorer and the gap is increasing as time goes on crazy world

An imbalance between the rich and poor is the oldest and the most fatal ailment of all republics
