There are many ways. You can invest in seed companies, or you can become a tractor salesman, or set up restaurants for the farmers because they will have a lot more money down the road. Buy yourself a second home by a lake in the farm belt, in the places where the farmers are going to be.
There are many ways to participate and to get involved – to hedge if you will. Becoming a stockbroker is not the best way. Farming is the way of the future. But don’t do it unless you like it. If you don’t like it you will find out it’s a lot of hard work and will go broke, like many other farmers. Certainly many have gone broke, committed suicide and so forth over the last 30 years.
Instead you can become a journalist covering the farming sector. Depends on what your skills and interests are. As you look at your life, figure out a way to orient it towards agriculture. If you want to sell, sell something to the farmers.
