In order to increase income from taxes, governments can usually most easily tax the middle class (provided middle class isn't too small of course).
And I state that free healthcare and handouts make people more dependant on the government, since governments can always provide some reason for decreasing the handouts or healthcare provided for various reasons. For example, perhaps at some point a government might decide to withheld free healthcare for civilians that refuse vaccination. Civilians at the bottom of the food chain would then feel more pressured in taking some vaccination in order to keep access to free healthcare of government handouts.
People dependant on the government will be more obedient civilians, so its likely many governments will want to move in this direction. Central Bank Digital Currencies will also give governments more control of people, so it will be the direction we'll be moving towards in the coming years.
