But I really can't tell how thus Investing in The Economy will help one's Country.
However, there are different ways in which one can invest in the economy of a country, one, it could be buying farming equipment to Farmers to enable them go into mass production of crops, which will result to less importation whereby adding value to ones currency, or introducing vocational skills, whereby citizens will come to learn basic vocational skills such as tailoring, Shoe making, welding and e.t.c with a little start up capital to enable them to become self employed and safe them from poverty as a result of skill acquired.
also, if you are investing in any form of business, it means, you are not a burden of your government and you are a valuable asset in uplifting the economy of your country. your contribution may not be big, but you are contributing positively to your country.
you can put up a small business, and in that manner, you are already helping your fellow neighbors or other locals in your area. it doesn't need to be big before you can help your own country, in your own small way you are already contributing to positive change.
