Monsanto will claim they are saving the world with their crops. When it turns out the side effects are making weeds resistant to herbicides, they'll sell you stronger, more poisonous herbicides. The new problems are worse than the original problems, and they require you to buy more of their products because only Monsanto has the formula for combating the weeds & disease they helped make. Making things worse, the genetically modified crops require more water and are less robust, in general. Monsanto doesn't give a shit about people, farmers, towns, health, etc.
The Clinton Global Initiative argues that to solve difficult social problems created by corporations you can sell corporations legislative access in return for cash to the Clintons, who then promise spend it in ways "helping" that are not 100% transparent.
Of course the laws benefit corporations exclusively, giving them rights and entitlements that only serve to make our social problems (poverty, joblessness, wage suppression, human rights, lack of health care and education) worse. Take a look at Exxon in Nigeria, it has been a disaster for the environment and human rights. Exxon can greenwash their culpability with a modest investment in the Clinton Initiative and in return gain critical political influence. That's just one of many, many examples. And the cycle continues.
If you think for one second that Hillary, Bill and Chelsea have any interest in eliminating the causes of our slow steady national decline, you are in denial. NAFTA, cruel welfare reform, banking deregulation, aggressive blood soaked foreign policy, believe it or not, you can trace these to the Clinton Philosophy, aka the 3rd way, which is just a media friendly word for a different kind of fascism.
Millions of lost jobs (and ruined lives here in the US) don't make up for slick videos shown to billionaires at an exclusive Morroccan resort.
Oh, and I almost forgot the answer to your question - corporations don't invest big money to solve social problems. They invest big money to gain legislative access for laws and regulations that will earn them a sizable return in profit, regardless of the human costs.
