Is there more value and respect for money in the society in comparison with good morals?

Sometimes we might see that money receives more attention and is pursed by more people than good morals. This is related to what Sandel calls "market society."Money originally was a tool, a useful tool. Good morals are formed in social interactions. Social life and practices embrace much more than money, and there is internal value in them. Value is something socially constructed.
In market economy, money thinking is extended beyond material sphere and into social, civic, emotional, moral spheres, and would corrupt or crowd out the internal values we form and treasure in these spheres. Gradually, such spheres with distinct values become colonized by money thinking and money value becomes the dominant value.
This is what is call by Marx as "alienation", and what Habermas calls "colonization".

The monetary system does not need to affect societies morals, but it can, particularly when working in conjunction with other forces, such as politics, governmental systems, and advertising.

A perfect example is the ethos 'greed is good'. Is greed actually good?

I would have said 'striving is good, greed is not'. However, when you listen to most people talk, without their admitting it, they believe greed is good (it's all about me - which is what greed is about). Don't get me wrong - there is an argument for greed is good. It's an easy argument to understand. It's a much more difficult argument to understand why it's not good.

That's because 'greed is good' is easily explained on a personal level, short term outlook, and on a very superficial level for society. 'Greed is bad' does not reward the individual (and 'striving is good' sounds like too much hard work), while the affects of greed require a willingness to consider (and be considerate of) society in it's entirety, the flow on effects of greed, and the long term repercussions.

So why do such a large percentage of people believe greed is good? It's not just because of the monetary system.

And materialism too, stems from the 'it's all about me' attitude (and is not so dissimilar to greed).

The real question is, where does the 'it's all about me' attitude stem from?

It does seems like money is more respected by the people that count. In other words, by other people with money.

You can't judge one society's morals against another. Morals are subjective based on each society. Asking which language is the best, or which culture's music is the most beautiful... these questions are meaningless outside of a cultural context. Each culture will insist their own ideas about morality are "correct" and that similar cultures are superior to cultures that are different.

I don't think this question makes sense.
