50% of Americans are absolutely not using 1% of resources. They control 1% of financial assets and liquidity as per private property law. 

You state thus yourself in parentheses and yet you still somehow make a point as if you don't even really believe it, or as though it's just a minor accounting error and the Venn diagram of Financial and resource data is close enough to a circle that they might as well be interchangeable.  

Most of the financially visible resources people use are not technically theirs because they, for example, rent it. Huge amounts of wealth is also arguably fake because much of it comes from inflated financial assets like, say, Tesla or Nvidia stocks. It's a game. It's not the real resource driven economy. 

Conflating financial power with resource availability is an absolutely massive mistake to make and I don't know how people keep doing it. I can only surmise that the common man's brain is so fundamentally broken in by Capital, like a horse saddle-broken, that he didn't even think to question if there was a difference at all? 

At any rate, the vast majority of resources are absolutely used by the working class globally. It doesn't matter how much money you have, it's impossible to eat the same number of steaks as 400 million average Americans. 

The problem with wealth is more in terms of power and the ability to control governance, law, and how resources are produced and distributed with a great deal of conflict of interest. 

The wealthy and powerful, to be clear, are still absolutely responsible to a vastly outsized degree since they control society and manipulate the lower classes.
