This is something every country has (no matter where, all have a form of VAT and sales tax) but a majority of nations include VAT within the price of the product whilst in the US that’s calculated upon checkout (so technically you are not paying $789 for a steam deck since you add tax, so that amount alone isn’t final).
So in reality, it’s closer to $820 or a game that’s $80 ends up to $95 but are either purchases possible whilst earning $15 per hour? Take the PS5: it’s ¥97,980 inc. 10% CT ($603) while the same is $650 but closer to $680 or more when you add SALES TAX, you can buy the same console in Japan since taxes are included.
Minimum wage has long fallen into the poverty zone in the US. As the saying goes, everything is expensive when you’re poor. And sales tax doesn’t help one bit. It’s a ‘flat’ tax meaning it doesn’t scale with income; a poor person and a billionaire pay the same sales tax for an identical purchase.
