It seems to me that if “affordability” is your primary goal, you would support steps such as: lower taxes (passed along by companies to individuals); lower inflation and lower gas prices (happening under Trump); less regulation (passing along lower prices to consumers); privatized healthcare, privatized education (enabling cost competition and price reduction); and the “accountability to customers” mentality of free markets rather than government monopolies with no price competition, no accountability to customers (think: post office, DMV).
Yet Mamdani, Sanders, AOC, and all the Democrats call for precisely the opposite. They will drive all prices up, making everything unaffordable and then still blame the capitalism they have outlawed.
Note that the ONLY people who support socialism are those who have never lived under it. If you live under socialism, you run for your life.
