Yes, the line between discussion and argument can be very blurred, it's a bit of a continuum I suppose.
Incidentally, I think those t-shirts are funny - I'd have no problems with wearing one at all.

And yeah, it's an image, but it definitely wouldn't mean I was jumping on any anti-capitalism bandwagon!
I think I was trying to illustrate above how trade would help the poor. It works similarly to foreign investment, but probably better - if you ask me. (as a lot of the returns to foreign investment go offshore, whereas the return to local export production stays onshore). Free trade at least in foodstuffs and light manufactured goods would assist these countries by giving them the ability to sell goods they are very good at producing overseas. Currently they are inhibited by protectionist trade bbarriers in western countries made along the "defend the local industry" argument, which if you ask me - is entirely selfish. (ironically, leftwingers are usually the protectionist ones...!) Poor countries can foten produce food much cheaper than can estern countries, and if their people were able to be employed in producing food for export it would help their economies and people immensely.
Theres so many factors though, the where the wealth ends up being concentrated is always hard to determine. In the poor countries, it is essential that they have solid legal and property frameworks set up, and that as the country develops it moves along a path of equal opportunity for all people, if you ask me. Primarily to avoid the corruption that plagues Africa (look at Zimbabwe and Mugabe's atrocities).
Random: You say that tax breaks suck the benefits from the economies. Well, this can be true to some extent, but they do give 100% tax amnesties, and there are still many other economic benefits that arise due to various multiplier effects. The multiplier effect is quite hard to describe easily, I'm not sure I did it very well above or can do it very much better without drawing graphs and diagrams! It's part of the 'economic cycle'. The key thing for a poor country is how much of income, welath or GDP/GNP is extracted from the country via overseas profits, and how much GDP/GNP is increased. I would argue that although a lot of what you say is true (re, terrible labour conditions, partial tax breaks, the power of big companies in negotiations) - there is no better alternative for helping poor countries. I would dispute that it makes them worse off.
In terms of the corruption of company boards etc, I think you have to be careful how you talk about 'profits'. They seem to have become a dirty word these days, as if it's BAD to earn money? Earing profit is just another way to generate wealth - it is a reward for taking on risk. It is a reward similar to rents on land resources and salaries on labour resources. You have to remember who gets the profits in the end.... ordinary people. Although some of these people are very wealthy - so be it. There are also many normal people who invest in large companies who benefit too.
In my opinion, the corruption of power is best dealt with in the legal system, through more openness with shareholders, openness with the public and greater transparency all round. Company law has been heading this way gradually over the past, which is a good thing.
A capitalist director or CEO is duty bound to be focussed on profit. They're employed to make the best return on the money risked by shareholders (and anyone investing in a dotcom sure knows those risks!) by law. In terms of factors outside 'profit', these should be looked after in other ways. Either through laws made to prevent activities that are bad to the public as a whole (e.g. dumping waste illegally), or through public initiatives or through the state welfare system/safety net. I believe this to be the most efficient way to balance things across society. We're moving this way - we haven't hard such large multinationals that long, in the context of 'history', so things are still developing.
These debates are so wide open, there's so much to say and try and articulate (and not do typos in) ... and undoubtedly, I have formed most of my opinions based on study I have done in Economics and Politics and reading I have done. I find it difficult explaining to people why I believe in the ideas I do without getting all economicsy. And then you're getting into the definition of 'efficiency' and 'allocative efficiency' and it all gets very ugly indeed.....!
