What is economic security?

Answer 1

Personal, regional or countrywide? I suppose it doesn't matter it is all basically the same.

It is being able to keep your wealth. The main way I know of is through diversification. Countries and regions need to diversify their economy to stay well off. This protects against if their is a failure in one industry others can continue to keep the economy going.

Personally, you need to assess the future in your savings to withstand changes in the economy. Sure, maybe nothing changes much and we will be all fine. Or maybe there will be hyper inflation, or economic crashes.

Economic security through Diversification would be making sure you hedge between:

keeping cash and bank accounts
keeping some foreign currency or bank accounts
local investments in several different industries
non local investments - from across the country
foreign investments
gold/silver or other valuables
real estate

Answer 2

It means, I believe, the ability to withstand instability in the economy.
