I mean, they do. The price of goods comes down. This is quite visible. Food, for example, went from 25% of income in the 1940s to less than 10% today as wealth concentrated among fewer and fewer farmers. If that wealth remained distributed, leaving every American still trying to run a small patch of land like they did in the 1940s, it would be highly inefficient and the price of food wouldn't have been able to decline.
But, okay, imagine (to stay with the previous comment's example) that the price of food remained the same and your income went up by $100/month instead. Your profit is still the same. Are you really any further ahead? Is having $100 clearly in your hand more apt to have you put it into the stock market, or similar, to captures wealth? Or are you still going to go out and spend that on a smartphone plan, or similar consumable, leaving no wealth to show for it?
You keep bringing up food. What of housing or healthcare? The costs there have risen dramatically at rates many times higher than inflation. Inflation adjusted the poverty line keeps rising while wages stay flat. I don't see how this is a sustainable system.
To be honest, I'm not sure we have actually seen a concentration of wealth in housing. The homeownership rate is almost at the highest point in history (it definitely was in 2008), which means that said wealth is spread thinner than ever. Further, construction of homes is still quite accessible to small business, so we haven't even seen concentration of wealth into construction to see lowering prices there.
We might even go as far as to say housing perfectly demonstrates what happens when you don't get the trickle down effect. Granted, those rising housing prices are not all bad as you can make money from the gains on the property and the construction of. This is the system you want to have everywhere, right?
But housing is also interesting because people have changed where they want to live. In the 1940s, ~50% of the population lived in the middle of nowhere. Today, ~20%. Now, people are willingly taking the $100/month they saved on food (just to stick with the example) and are applying it to the rent in the big city so that they can have the opportunity to live there. If they were happy with 1940s-style living, and opted for a home in the middle of nowhere, they would be able to retain that $100/month and capture wealth with it. Like the smartphone, this is consumer choice to give up the wealth to get more (to live in the city).
As far as healthcare goes, I'm inclined to agree that wealth has been more apt to concentrated there. But like people choosing to pay more to be in the city, people are choosing to pay more to have state of the art healthcare. Would you really want to go back to 1940s style healthcare at a lower cost? I'm not convinced I would, even if it helps my balance sheet. The gains are still there, but utilized instead of being stashed away into wealth.
