The number of combinations of choices in social and human affairs is pretty much infinite so politics in a real Democracy could theoretically be infinite-sided (though only if there were no “representatives” of citizens and people directly voted on everything - i.e. direct Democracy)
Because the US isn’t really a proper Democracy (more like an attempt at one), the vote itself in American has only 2 real options, but there are other ways to expand the number of choices because the two main parties in America are umbrellas for ranges of possibilities and they do have somewhat democratic (rigged, but still with more choices than the actual vote) internal selection systems in the form of Primaries.
If one properly analyses it, it turns out the presidential selection system in the US is really a multi-stage affair in which two of the stages - the Primaries and the actual vote - are open to the public (though there is quite a lot of selecting going on behind closed doors even before the Primaries).
So if people participate in both Primaries and the actual vote, they de facto have more choices than 2.
Also another thing to keep in mind is that this is a cyclical process and the outcomes in one cycle - i.e. who won and by how much - influence what happens in the next cycle so the vote itself defines not just what happens in one election, but also which choices will be made available - i.e. which candidates will be fielded - in the next.
All this means that if one actually cares and makes an effort, there’s more “Democracy” to be had than it might seem at first sight and the vote itself has more influence than just that immediate choice, so anybody claiming that “you have no choice but to vote lesser evil” either has a simplistic view of things or are purposefully trying to deceive others.
This is without going down into the whole local politics and civil society participation, which in the US is almost as livelly Democratic as in Europe.



Well, in Accounting terms, once you sell your investment you have realized the gains on it (and if you’re a person or a company, are now liable to pay tax on those gains), even if you use the money from the sale to buy the same thing again.
Gains on an investment which hasn’t been sold yet are unrealized gains (in common parlance “paper gains”) and don’t really count in accounting terms until you sell that investment so you don’t have to pay tax on it.
Amongst other things billionaires use this to pay no tax when the share value of the companies they own goes up: if they need money rather than sell their share holdings they take loans using the shares as collateral, and because the shares aren’t sold any gains aren’t realized, hence no tax is due.
