Best way to deal with what OP has mentioned, is to spend wisely and save. And from the savings, wisely invest most it. There is a difference between saving and investing. And there is a difference between simply investing and wisely investing.
And in my opinion, nowadays is is actually the ones who are employed in corporate companies, that feel their future in uncertain. We internet marketeers know we can simply move from one product / service that no longer sells, to the next product / service that is currently selling and we always keep finding newer methods or strategies to market or sell products or services, because there are and always will be newer and newer methods and strategies, and there are and will always also be newer and newer products and services to market and sell. And to implement or try anything new, we do not need any "boss's" "approval".
Real life example : In 2020 when the world was under the pandemic lockdowns, some (actually perhaps many) people lost their jobs. During the exact same time, there were internet marketeers who made a lot of money marketing (online), face masks, sanitizers, etc. These internet marketeers did not see the pandemic lockdowns, etc as some uncertain event that would impact their earnings. So, internet marketeers (may be not all) do make money no matter what is happening, as it is easy to move from selling one product, to selling some other product. There is always an opportunity in every scenario, for many internet marketeers. Every scenario, every challenge, every new problem, results is a new solution by some inventors and some businessmen and then the internet marketeer would just market, sell those new solutions. And nowadays for solutions to problems, the solutions are invented or created and released for usage, quite fast, so the marketing opportunities can also be grabbed quite fast.
