The only way that something like socialism can work is if we reduce our desires against what we need.The biggest issue is that there is no idealistic middle ground. Socialism is unworkable, especially in an ever-burgeoning population. Everyone having a fair slice of the cake doesn't work if there are more and more people who want the cake; and to further the analogy, the thinner the slices become, the further the decrease in the quality and standard of life becomes.
Arguably, capitalism is equality in the sense that opportunity to exploit it is equal for everyone. I think Jeff Bezos is a grotesque individual, but I don't begrudge him the money he has earned. I begrudge him not paying what can be considered reasonable amounts of his capital back into the system gave him the lifestyle now afforded to him. It's loopholes that need to be addressed, not capitalism itself as a start line.
Disneyland has brought joy to millions of children worldwide. But it only exists because of capitalism. It is the brainchild of imagination and captilist venture. We're on a football forum; the sport as a joyous spectacle, with all the glitz and glamour attached, only exists because of capitalism and greed. I guess my point is, many have enjoyed their life precisely because of capitalism.
The question is simply this, do you want everyone to have a fair slice of the cake? Or do you want everyone to have a fair chance of baking a bigger, tastier cake than others? Capitalism is ugly, but sadly it's the only thing that works.
Socialism works to provide a basic standard of living, for example the essentials such as housing, food etc. However, that falls apart when we start to blur our definition of what a good standard of living is. A good standard of living for many is having a bigger house, a better car, a bigger TV, having a few meals out and a holiday. These are fundamentally capitalist needs which you would have to give up because of equality and lack of resources. You can't have a few people going on holiday to Barbados whilst the rest go to Skegness, and no system can afford to send everyone to Barbados.
Would people willingly give up everything these luxuries and everything they have worked for in place of a socialist system which provides all of their basic needs but very little else? Of course they wouldn't, we're wired to protect ourselves and improve our own standard of living first. If this wasn't true then why do people want promotions or try to get better jobs? Do the champagne socialists really understand that such a system will ensure that they never drink champagne again?
The socialists won't tell you this but they all yearn for authoritarianism and dictatorship. The reason why is because ultimately the main obstacle to their implementation of socialism is you and what you want for yourself.
