Under the economic model Bernie Sanders and Collectivits support, the living conditions the majority of people experience will be an incredibly lower standar of living than what the majority experience now.
Sanders economics puts the needs of the poor over the rights of the individual. His belief goes to the extent that he believes people's choices should be limited between necessity and want. And even though the population grows every year, and more jobs are needed, there's no need to "grow" an economy.
Here's a quote:
You can't just continue growth for the sake of growth in a world in which we are struggling with climate change and all kinds of environmental problems. All right? You don't necessarily need a choice of 23 underarm spray deodorants or of 18 different pairs of sneakers when children are hungry in this country. I don't think the media appreciates the kind of stress that ordinary Americans are working on.
To remain competitive the US can no longer ignore blatant shortcomings in national management, capitalism has failed and must be regulated, it can not regulate itself. Sanders have suggested looking to the Nordic model for some of the answers, and when hard facts support the success of these systems, why shouldn't we? The Northern European countries are some of the most successful countries in the world. Bernie Sanders want the American people to prosper. To achieve this he expects the rich to contribute as well. If you can't live on a full time job, it's no better than slavery.
