Well, the poor seem to have smartphones as well XD — Uganda for example has 54% smartphone ownership. But in terms of vaccination rates, education, access to clean water, access to electricity yes things are ever improving if we look at statistics on global wellbeing. "In 1981, 44% of the global population lived in extreme poverty. By 2019, that figure had dropped to just 9%." So inequality may be huge today, but it doesn't mean the bottom hasn't also risen dramatically.
