I'm sorry, what asset classes did you invest in? Because Trump and the Covid stimulus were both very beneficial for my investments. Sure, the market has taken a beating of late but it most definitely has not erased years of gains.
If you hold an index fund like VTI though, that's done well. These last few months really highlight the dangers of stock picking, even with big companies.
That said, it mostly tracks the stock market, just sort of "dampened", since it has a mix of other stuff. The downswings from both Trump general craziness and COVID recovered, eventually (I was certain the downswings for things other than COVID would … COVID, I was less certain about, as this is probably the biggest thing that's ever happened in my life), of course, but it sort of feels to me like a detour where after several months you're like "yay, back to where were were". I'm a SWE, so I'm above the stimulus cutoff. (But that's the thing… well off enough that most things are fine, but … the housing market, practically speaking, wants millionaires, not "people doing decently".) But AFAICT, the cost of a home is keeping pace with gains in the stock market, particularly so if you're not in a sort of undiversified-yolo-all-in on the stock market position, which I've been told is poor form. But that makes investing for a home sort of a losing prospect: it's more just a savings account at that point, with the investment gains limiting the ground being lost. Conversely, AIUI, this is why there is so much speculation in the housing market; if the stock market were outperforming it, people would be speculating on that, instead.
What boggles my mind how anyone not in tech is making do. What I see both from people I know, and in the news, suggests they're really, really struggling.
