Parents in the past did not know much about investment, so they preferred to save their money even though it would be eroded by inflation which would lose its value over time. The only option I often hear is gold and that is only done by a small number of people.
Now investment should be something that is no longer foreign to parents, so they can learn it and teach it to their children. Moreover, in this era, it is not difficult to find information amidst massive digital developments.
True, many parent in the past lack knowledge about investment way increasing assets for longer time except their recommended for investing at bitcoin or land. Lack knowledge about technology and not learning more about new way for investment I think problem why many children can't learning more about investment way which one have faster for increasing assets. Best investment or financial education from parent in the past for investing or saving money in gold or buy any land although for both kinds keep worth it just take more longer time.
Right now, easily for accessing internet and for children can learn more about financial education using mobile phone, not difficult if want learn more about financial education but guide by parent make all easily for children start their financial education from home. After reach senior high school will easily to learn about financial education.
