In one way or another, societies will have to tackle this problem or there will be some major social disruptions such as widespread civil unrest, radicalization, mass migration, revolutions, and civil war. All of these possibilities may seem like on-issues to you in your country now, but we already see their beginnings and the trend towards increasing the gap continues.
To make this clear, I'm not talking about politics. If the trend is not stopped, there will be problems regardless of what political opinions you have.
"You have 1,000 times more wealth than a poor person so you can't say it's bad that someone else has 1,000,000,000 times more."
You know what, I absolutely can.
It's about the allocation of resources, efficiency of the marketplace, assymetry of wealth and political power and how it affects the democratic project we've all been engaged in globally for a few hundred years.
Economic systems are human-invented games; the rules can be rewritten. Things as basic as property and trade are human constructed concept with fine human-constructed nuances (people aren't property for instance) The laws are a chosen set of axioms that can be voluntarily changed.
The question is if this is the outcome we'd like to see from an optimal set of rules. Can't we design something better that doesn't lead to mass extinction, climate change, mass poverty, and a system that crashes the global economy every 10 years?
These are open challenges to improve things, that is, if we choose to take those challenges on.
Getting back to your points:
> food
We already (can) produce way more food than we consume. The main problem is distributing it and the lack of economic incentives to make this distribution global and fair.
> housing
We have the tech and resources to provide everyone adequate non-slum housing. It's again a problem of global and fair distribution. More than that, more people need to accept that we need more high density urban environments. This point will come back later :)
> energy
From an energy point of view, we're kind of at the "food" point. The real challenge is converting energy production to renewables. Which brings us to...
> not wrecking the planet
We absolutely have all the tech and know-how to not wreck the planet. But it's a tragedy of the commons.
Not wrecking the planet is the final end game, the ultimate cooperative move. Heck, it's the final anti-zero sum game move.
