This is a completely unsurprising outcome to anyone who has actually been poor and spent considerable time around poor people. Being poor is both a mindset and an actual socioeconomic status. Giving enough cash to marginally change socioeconomic status will not change the mindset. The biggest thing we could is actually improve financial literacy in the US by mandating it as part of our standard educational curriculum, but that will never happen as so much of our economy is built off exploiting the uneducated, who are almost always poor.

I started in pretty much the same circumstances as most of my peer group, with one distinct difference, my dad had gone to school for business and accounting and was a bit miserly, he instilled in my an understanding of the value of a dollar and the right skillset to track where my money is going. That small little difference is what separates the fact I will end up dying a multi-millionaire and my peer group are mostly going to end up dying broke. Obviously there's hundreds of thousands of little choices we make every day of our lives that nudge things in one direction or another for your financial trajectory, but starting with a grounding in financial literacy is literally life-changing.

It's not cash that people need, it's education, so that they can actually effectively use the money they already earn. I started saving from my very first job as a teenager, and have never stopped. The median American net worth excluding home equity is negative, mine has never been negative at any point in my entire life, from before I was an adult, despite growing up low-income in a rough area.
