It all comes down to how you propose going about achieving that.
As long as people have bank accounts and can accumulate wealth, there will be a small percentage of people with savings and large percentage of people without. You can take money from people who have and give it to people who don’t, and we do quite a lot of that already.
As long as there are private schools which you can pay to send your children, and tutors your can hire to help them learn, and housekeepers you can hire to have more time to spend working or with family.... then those people who got high paying jobs and worked hard and saved money will be able to give their children a significant advantage in the world, in theory leading to higher functioning, higher achieving offspring.
When you consider that the top 1% of taxpayers pay more than the bottom 90% combined, I think that’s far from this “knives out” picture you are painting. The top 1% very literally have their wallets out to pay it forward.
