Seattle feels like “No income tax but a capital gains one, and a payroll levy visa holders can opt out of”, while St. Louisis “An independent city that divorced its county in 1876, a 1% earnings tax on a line you cannot see, and the only state in America that exempts capital gains”. Climate is a real differentiator: Seattle — temperate oceanic — grey and drizzly from october to may, then a dry, bright and genuinely excellent summer. St. Louis — humid continental — hot humid summers, cold winters with ice storms rather than reliable snow, and a genuine spring severe-weather and tornado season.
