This is defined as people living on less than a dollar a day. Yes, it has more than halved in 30 years. Congratulations. I totally see how this progress actually over half a century relates to the world's richest getting an extra trillion in one year. Yep, makes sense to me.
Your tone sounds sarcastic but I don't see the justification for it. The number of people who are actually hungry and malnourished has gone down significantly, and far more people are vaccinated today then 25 years ago, and far more children can go to school and literacy rates are up.
Is it easier or harder to afford basic foodstuffs? Do they eat out (luxury) more or less? If they own a home, is it larger or the same size? Who travels more? Who has better healthcare? Who spends more on entertainment? How much do they spend on the family pet? Who spent more time furthering their education?
All of these are measures of wealth, and the modern "regular" person would be wealthier in every one of these categories. And that's not even factoring in advances in technology that make the quality of life of a person better even if there share of societal wealth goes down.
> Is it easier or harder to afford basic foodstuffs?
Processed foods are far easier to afford, but they are extremely unhealthy. As for other basics, many have gone up over the last 50 years.
> Do they eat out (luxury) more or less?
Women now work. 50 years ago they did not. Less time/people to cook at home. Not like everyone is eating at steakhouses. They just don't have the time so they go to Chipotle or McDonalds or Panera.
> If they own a home, is it larger or the same size?
Most people own legacy homes-they are the same size because they are the same homes. New builds are building bigger houses but what "regular" person builds new homes?
> Who has better healthcare?
This has more to do with advancements in medicine and technology than people becoming richer.
> Who spends more on entertainment? How much do they spend on the family pet? Who spent more time furthering their education?
Furthering education is largely on credit, so this is a bad measure.
> and the modern "regular" person would be wealthier in every one of these categories.
Nope.
It's impossible to separate people becoming richer from advancements in technology. We didn't grow GDP by 77 times, because we work 77 times harder.
Improvements in underlying technology are what help us create more wealth. The problem is that the new wealth being created and benefits of that new technology is being shared so proportionally.
Try to do that today in the same area. The foremen at the same sugar house could never afford a regular residential lot, much less the a house to put on it. It would take them 20+ years to save the money.
Inflation is a regressive feature of modern currencies. It transfers wealth from lenders to borrowers and away from investors. The degree to which it does so is a function of the amount of wealth one has.
When you read stories that Apple (or whoever) has $X billion "in cash" it's not actual cash. They keep some around in money markets and the like for near term expenses, but the majority is in bonds that pay more than inflation. In fact, if Apple were classified as a bond fund they would be the largest in the world:

In the year 1900 Global GDP was 1 Trillion. Today it is 77 Trillion.

In Layman's the Global Pie is growing. The number of people living in extreme poverty has fallen DRASTICALLY over the last 25 years. https://twitter.com/humanprogress/status/913901718823489538
So the people with the smallest piece of the pie are slowly getting a larger piece, but the people who already have the biggest piece of pie are getting even bigger pieces faster. But because the pie is growing, it doesn't mean that their larger piece is making someone else get a smaller piece.
The only people who have a proportionally smaller piece than they used to are in the middle class. Which is what happens when first world work more closely with developing nations. Taking more people out of extreme poverty but putting slight downward pressure on the middle class.
