Money doesn't get invested into projects that 'do things honestly', it gets invested into whatever is deemed to make the most profit. There's plenty of people who provide loads of value to those around them (emotional labor, child care, etc) and go largely unpaid. Unless you can generate massive profits, there's little incentive for capitalists to care, and it's capitalists who have all the money and political influence.
That's quite the broad brush you are painting all capitalists with. There are many ways to be successful many forms of capitalism, some degenerate yes, some not so degenerate. It is up to good honest people to set the example, because yes the greedy ones will always greed away. History has shown me that it doesn't matter what economic and political system is instituted, greed will find a way to exploit the good intentions of those systems.
>It is up to good honest people to set the example, because yes the greedy ones will always greed away.
A focus on 'greed' or 'honesty' is missing the mark on what I'm saying here. We currently have an economy built on a foundation of historical expropriation, enclosure, colonialism, subsidy, regulatory capture, rent-seeking, etc, and heavily biased towards the resultant monopolies/oligopolies. As a consequence, prices are set at this inflated level of profit, and those who perform labor outside of the interests of these corporations typically aren't able to afford the costs of living (especially without breaking the law). "Greed" isn't really the issue here; the issue is systemic privilege born through violence.

It's pretty intuitive that a political system is generally going to be favorable towards those who instituted it, outside of happenstance benevolence from a political elite.
