Most investors are putting money into investments to make more money. The best usually consider job creation as a worthy byproduct of their investment. The worst either don't care about jobs created or lost, or they seem to revel in job loss, pollution, deforestation etc. that their investments cause.
Capitalism allows either extreme. We are free to choose good or evil. Anticapitalists note the disregard for workers in this system and conclude that the system must be evil if we are allowed to do evil. This is probably how communism and socialism got started.
I propose switching this around. Let's make job creation the number one purpose of our investments. Making more money can take a back seat to it.
The most direct way to do this is through entrepreneurial activity. Starting or buying a business directly creates jobs and the person running it can keep the same workers as long as they want to be employed there. They should get raises and good benefits, and if they go someplace else to work they should be able to take that experience with them. They shouldn't have to start again at the bottom of the pay scale and work their way up again.
The next most direct way of creating good jobs is to buy bonds. These could be corporate bonds issued to fund a specific project or merely a way to finance expansion. They might also be government bonds issued to pay for roads or bridges, or other purposes. Financing through bonds is a good way to create work for union construction workers as well as architects and other white collar workers. These good paying jobs allow the workers who fill them to buy homes and cars, pay for their kids upbringing, and save for retirement.
The third and most indirect way to finance employment is through stocks. This being the most indirect way, it is also the most complex. There are two ways I can think of. One is to purchase IPO's. Just as the company becomes public there is the chance for growth and financing this growth will help it. The second way is to vote, as a shareholder, for better wages and benefits for the workers, lower compensation packages for the upper management and fewer layoffs. There are always disastrous stories in the media about corporations that go out of business or get sold giving a few at the top enormous golden parachutes while the rest of the workers and investors get robbed.
Changing the order of priorities in a portfolio of investments can have a profound effect on the investor. Rather than being a greed driven person who doesn't care about anyone, they can become a more ethical person. They are probably going to live a simpler life and have better relationships. It's not necessary for them to live like paupers or hermits, simply that they put others' lives ahead of their own desire for material wealth.
Obviously there are bad vestments in each of these categories. There are entrepreneurs who only have young people working for them for the simple reason that they presumably won't demand as much money. I knew of a woman who only had part time workers, so she didn't have to pay benefits, but she bought a brand new Cadillac each year. There are a number of jobs I've had since childhood where the people hiring me could have paid me better but obviously didn't for the simple reason that they wanted to keep more money for themselves.
There are bad bonds as well, like the ones that were all the rage in the 80's. They called them junk bonds, and generally they broke up companies, laid off thousands of workers and concentrated all the wealth in them at the very top. Obviously, that's of the opposite of what I want.
There are companies that do something very similar without issuing bonds. They lay off thousands of people the same year that they give gigantic bonuses to their top executives. I often wonder if they really think these two things are going to go unnoticed by the press. Also, my dad once had stock in a company that got sold, and for a couple of weeks there was no trading on that stock. When the negotiation was done the investment was only worth a fifth of its original value and the CEO of the company that got bought took an eight figure bonus. Another case of the rich stealing from the poor.
