You think this will change anything? I doubt it, there would just be an increase in the job requirements due to credential inflation.
Imagine instead if every single individual could: read and write at a high level, think critically, compare loan options rationally, perform their own limited legal research (tenants' rights, welfare eligibility and application), plan their own investment strategy for retirement, etc. It would be a huge boon.
Poverty could be behind these suicides as it can cause a tremendous amount of stress which may lead to chronic depression and anxiety, and for temporary relief people look to drugs/alcohol and those with addiction are at higher risk for suicide. AFAIK, most addicts are poor, unemployed, and uneducated and I see a clear correlation between economic status and abuse.

And, here’s a related study by Princeton academics who won the 2014 Nobel Prize for economics.
