So recently I came into a very slight inheritance (nothing that lets me not work or anything) but a nice change from my previous level of "I would need a payment plan to buy anything more than $1000" as my access to liquid cash is quite small. In general I've saved 20% of my take home pay, maxing out a Roth IRA each month and saving the remaining in my checking account, and keeping a general budget/tracking everything. In the past, when I first moved out of my parent's house and was living alone, I had figured out I basically couldn't buy anything that wasn't an absolute essential if I didn't want to be reaching into my alloted savings and that led to an eventual "I have $30 in cash in my account until next pay period" kind of shit. I have always been sure to fully pay credit cards/treat them more as debit and had a great credit score, and even now am in the 800s so I figured having almost non existent liquid cash available was more the norm in today's society.

Anyways, I've honestly only kept this inheritance in my checkings account in a virtual money under the mattress kinda thing, as I just have a natural aversion/ick towards the stock market and every other aspect of finance in capitalism, and have ignored my bank wanting to schedule financial advisor meetings and such. But I do recognize the kinda tightrope walking necessity of living in a capitalist society, and without things like investments you are 100% doomed to work til you die (which may be the case regardless of financial decisions but work with me here).

So I ask, is there any kind of hexbear/marxist approved financial strategies out there? Like I should take x% and put it in y kind of thing? Or is the money under the mattress equivalent the way to go? Again, I'm avoiding just googling "how to divide your money" kinda stuff because it's coming from total capitalism is eternal kind of places.

Thanks!
