Rather than working for all, power and public policy is increasingly influenced by wealthy elites that are able to bend the rules - and hijack democratic institutions - to their favour.
Here's something we're rarely told growing up: our world rewards wealth, not hard work or talent.
When men and women, boys and girls, are denied the right to education, the right to own land, the access to basic services like healthcare and clean water, a fair price for the crops they grow, a fair wage for the work they do, or the right to be part of making decisions that affect them, the result is poverty.
To build more human economies in Africa, governments must be far more strategic, wise, and forward-looking in their expenditure and build diverse economies that are going to deliver the jobs for the next generation.
Having an economy that works for the 99% is achievable.
African countries lose billions every year because of tax dodging by big corporations and wealthy individuals. They lose billions more from overly generous tax incentives in a misguided belief that this is the only way to attract foreign investment.
We have international organizations for health, trade, and football - even for coffee - but not tax. Why not?
Crucially, African governments must ensure they prioritize the eradication of tax evasion and tax avoidance.
A global tax body would give all countries - not just the rich and powerful - an equal say in how the global rules on taxation are designed.
Fundamental is the need for governments to protect the space for citizens to claim their rights, organize, and express themselves.
Poverty is rooted in injustice.
Progressive taxation can offset the effect of growing inequality.
Governments should end the extreme concentration of wealth in order to end poverty. This means tackling tax dodging but also increasing taxes on wealth and high incomes to ensure a more level playing field and generate the billions of dollars needed to invest in healthcare, education, and job creation.
High corruption and the influence of big business and the wealthy elite keeps the poorest Nigerians trapped in poverty and cut off from the benefits of economic growth and basic services. Some people - searching for the means to survive - became vulnerable to groups like Boko Haram.
Women, men, and children have fundamental rights to humanitarian assistance and protection. Yet far too many states block aid and attack their own citizens, and too many others - including some of the world's wealthiest countries - turn their back on those fleeing conflict and violence.
It's happy and secure people who the are most creative.
Our economic system has enabled companies and individuals to use their power and influence to capture and retain an ever-increasing share of the benefits of economic growth while the benefits for the poorest in society have shrunk.
We treat a planet at crisis point as an externality that can be shunted into a future generation. We continue to act as if we had the natural resources of several planets, not one.
Developing countries can make great strides towards more progressive and effective taxation and spending through action within their own borders. But the damage caused by exemptions, loopholes, and tax havens requires action beyond national borders - it requires international action and cooperation.
