As someone who never has to make another penny in his life, I have no interest in investing or paying any more taxes than I have to. Not having an income helps my tax liability. My efforts are investing in how cheaply I can live in an off grid home and raising my own food.
I am keeping my funds liquid in physical gold which does not have a tax liability. The value is lower right now but you don't lose money if you don't sell low. I don't need to touch any of it, so I am going long term. That is the plan, never need to cash out.
When our country reaches the 30 - 50 Trillion mark in borrowed money and our short term debt financing is faced with higher interest payments not to mention more obligations to the retired citizens, we will have no other choice but to print money like crazy.
The rest of the world will move to another currency and Gold will be the standard to keep it honest.
The stock market is a great place to be if you want growth, I don't need growth, risk, or taxes.
As everyone's utilities rise, my solar will keep providing me with what I need. If you have no bills, you need no income. If you have no income, you pay less taxes.
I find not having a horse in the race comforting. To quote Forest Gump, "One less thing to worry about".
