Capitalism seems to ecompass a big group thing but with specific bad tactics over individuals... greed seems more general and a bit more individually orientated or smller in scale as a conscious choice in clusters of individual behaviour...
btw ... I never know with your posts if it's mostly for you or actually you want longer answers (seems can be both or on sliding scale mix - so it's easy to ask short and then say it's too long or ''I didn't mean that' or think someone is being ''xyz''')... but anyway disclaimer aside that was my answer above and this I might have to copy and paste for you posts until I'm a bit sure or learn your ways (if possible)...
