The good old "free will" of capitalists is why some people argue for socialism - money REALLY does talk, in the sense that lawmakers and politicians get paid by those with the money to adjust laws to their interests.
The medical industry is a monopoly. There are laws approved now that if a doctor comes along and offers treatments at a much lower costs in a private clinic, he has to seek approval from certain big dog hospitals before he can open these prices... that's the law, but you think they're going to approve a service far cheaper than theirs, even though it's the exact same thing? Heck no... but money and lobbying is how these laws are set in place to protect the interests of those in the monopoly.
This is illegal, there are anti-trust laws that forbid this practice... but money talks, and the judge looks the other way. And so, if capitalism is about making more and more and more of yourself, accumulating what you can because you are free and dog gone it, therefore yes you can... the temptation is there to maximize profit by cutting competition. This was a runaway in the US in the late 1800s, lawmakers saw the problem and addressed it, but here we are.
This is not the "good" form of capitalism, which allows competition in a free market in which the consumer drives the demand, rewards good products by buying them and shuns bad/outrageously expensive products. That is where it must be balanced with socialist aspects, ie some form of gov. cap and regulation... which again has BEEN addressed in the past, but special interest and money has overlooked these laws meant to protect the free market.
But then with socialism, I can see how that doesn't work in its purest form precisely because people have desires, they want more, and they don't want the same as someone who does virtually nothing... that's not fair, they want something to show for their harder work.
If anyone wants articles, I can google and find some that say it better than I can.
If men can be trusted with riches on average, and wealth does not tempt one to sin, then why out of ALLLLL the Israelite kings, we only have a small handful that were righteous? I wouldn't stop anyone from accumulating wealth with hard work, only stress they should be wary of a hard heart... it's sooo easy to get into a "well, I worked long and hard to get here, I'll enjoy my goods and if people want the same, they can do the same." It's easier than you think.
