Assuming the article is true... if a Mustachian has 10-15 working years left, would a Trump presidency and market crash now, and for the next few years, be better for their FIRE date, to buy low? There's plenty of reasons not to vote Trump, but I'm not asking if they should favor Trump or not for any of those other reasons, but would a Mustachian, acting purely from selfish reasons only related to their portfolio prefer a Trump presidency and corresponding market crash?
They would also have to assume that after the Trump crash there would be a Trump economic boom.
Or assume he only got 4 years, and the damage he did would be outweighed by getting to put in money low.
Putting money in low compared to what - the markets after he leaves office? That does assume that there would be a big rebound after, instead of prolonged negative impact to the economy. Redbirdfan's list, for example, could lead to much longer impacts.
It also assumes that this hypothetical person does not already have significant amounts invested. If they did, the markets would need to increase enough, quickly enough, to make up for their initial loss. Is that guaranteed?
It also assumes that a prolonged crash or greatly increased volatility does not negatively affect the economy in other ways. This person could have lower wages, a harder time finding a job, or even get laid off.
If the ACA gets killed, both expected and unexpected medical costs could rise greatly for an early retiree.
I think most of the time, people overestimate the impact a president can have on jobs and the economy. In this case I think it's the opposite.
Besides, if we're talking true Mustachianism, not just the wanting to retire early part, we need to take into account the non financial parts of the MMM philosophy. Saving the environment? You don't want Trump in charge, even for four years.
