I vote for small-scale business. Of course, people who choose this way may face some difficulties. For example, it will be hard for a businessman to find additional funds and get credits before he becomes famous and trustworthy enough. But on the whole, private enterprise is great. When your business is considerably small, it’s easy to change your plans if the situation on the local market alters rapidly. Also this form of economic initiative allows us to reduce management costs – you can run the business alone and it will be OK! Small-scale business gives more opportunities for showing our creativity and trying all possible ideas – we are our own masters! The turn-over of capital is faster and it’s an advantage too. Big business doesn’t attract me. It’s hard to become a business giant and it’s also a great responsibility – you have to employ a lot of people and guarantee stable salaries and wages.
Salary and wage labor is the most traditional way of getting money and, maybe, the most stable one. Still if you are a teacher, it will difficult to live on salaries alone.
As for investments, you should be a very enterprising person to use this money-making area. You must have WHAT to invest and should know WHERE and HOW.
I think that an ideal way is a reasonable combination of several ways. For example, a person works at a state establishment and gets a small salary but serves the society. At the same time he or she has an additional business-project that helps to earn real money. It’s possible nowadays, I’m sure. And if the person has what to eat and the business is OK but some spare capital is still left, it can be invested in real estate, children’s education and so on.
It’s always possible to earn money if you know how to do it and choose honest and smart people as business partners. I’m not sure about “a lot of money” though… If we admit that “a lot” means “millions of dollars”, then it’s a matter of luck, I think.
