In a system that lacks competition...

Look at the best car that the USSR made vs any car made in the States.

Without competition and struggle, the entire creation engine dies.

A group of scientists cannot out compete one Nikola Tesla.
No matter how much they cooperate.

So, we cannot survive without competition.

However, if all is competition, then the slowest people die.
One should not have to compete for food, when there is an abundance of food.

The real road block from people feeding themselves is property taxes and the FED. Both have conspired to make land ownership out of reach of the poor. Neither of these entities are "capitalism".

So, we also need a system that gives the means of producing food and shelter to every man.
