Take Canada as an example. We've got the House of Commons, which is where all the elected members of Parliament sit, effectively similar to the US House of Representatives. But then we have our Senate. It's regionally distributed; 24 each to various regions plus 9 others for the remaining smaller bits. But it isn't elected. They're appointed, by the Governor General, based on recommendations by the PM. And they serve as long as they want, or until they hit the mandatory retirement age of 75. In practice, it's generally an end-of-career reward type thing for politicians; it's a cushy job but the Canadian Senate has a lot less power than the US Senate, and is decidedly a step down in power and influence than the House of Commons. While bills have to pass both houses to pass into law, it's basically just the House of Commons that gets to write bills, so the Senate is meant more as a sober second thought without as much partisanship influencing anything (since Senators may have been chosen from within a party, but no longer run for office, they're free to vote on their conscience rather than needing party support).
It's an imperfect system, but better than the American. I'd prefer the Senate be made into essentially a reward for non-politicians who've done good works in Canada; get more diverse voices into the process. Senate reform's an actively-discussed topic, here, though.
The advantage of a bicameral system is that members of each House have different selection processes and thus are less likely to respond the same way to changes in society; that reduces partisanship (in theory). The American system leaves so little distinction between the two this doesn't work out, however.
Capitalist markets.
Markets, in general, are just distribution systems. Their primary goals as systems are derived from their economic system; capitalism seeks to exploit for the profit of capitalists, a socialist market system seeks to balance benefits between workers and consumers.
