The are no right or wrong ways to handle economies, there's degree's of control ranging from laissez faire based free trade to localised protectionism. Whatever ideology our society subscribes to, there are always winners and losers, in that sense there is no right or wrong, or good or bad. Just winners and losers.
If you want to protect your wealth, which by the way in monetary sense are just tokens of exchange, you need to understand each economic theory and their applications, then try to predict how the big dogs will play their next hand. It's pretty obvious what to do in a world where the top 1% manipulate most forms of wealth for their own gain, whether it is cash, bonds gold or stocks. You need to realise that monetary wealth is imaginary and begin to invest in other forms of capital, whether that be learning how to grow food, fix and make things, own and or productive businesses etc. If society collapses tomorrow as a result of the massive bust that will follow 90 or so years of Keynesian debt fuelled economics, you don't want to be the last many standing hoping that your imaginary horde of wealth will provide for you in retirement.
Be warned, the big one is coming.
