In a socialist society "too much" can only mean "more than is sustainably produced." If people decide that they (individually and as a society) need to over-consume then socialism cannot possibly work.

Under capitalism, there is a very large industry devoted to creating needs. It tells us we need toilet seat warmers, nifty gadgets (that don't work), new this and that, and attempts to convince us that our human worth is dependent upon our material wealth. Capitalism requires consumption, whether it improves our lives or not, and drives us to consume up to, and past, our ability to pay for that consumption. On top of that, goods are not built to last because that would interfere with profit making.

Socialism will be a very different society. Goods will be built to last. The buy-buy-buy advertising industry will no longer exist. People may decide that they have better things to do rather than produce goods that are widely seen to be extravagances. And people may discover that more material goods don't make them happier.

Society already has the knowledge and technology to satisfy all of our basic needs sustainably. There is every reason to believe that socialist society will supply every human being with all the material goods that they need for a comfortable, pleasant, enjoyable life.
