The poor people wouldn’t feel compelled to donate their money, they’d just keep it and fend for themselves, hoping they don’t have to do anything. A lot of times people in the lower class already struggle with taxes, which sucks, but if they don’t have to pay, why should they care what the country does, it’s not the their money that’s being wasted, it’s the rich. The rich would just be able to hire private securities, especially in rich communities. The rich would then have total control of policing, because they’re the ones paying the police. Manufacturing companies would do anything for cheap labor, so lets say now they ‘volunteer’ lots of their money to fund the courts and police. They could essentially have as many people as they want arrested, since they fund the courts and police, and just put them in for-profit prisons with no pay. On the whole most people want to stay alive, so if you give them basic necessities, such as food and a place to sleep, most people will try to stay alive, and if not, they could always arrest more.
The ‘private sector’ could just force people to pay for roads, by saying if the people don’t pay up, the roads could go into disarray and they could lose their jobs. Or those megacorporations could work together and start hiking up prices of products in order to pay for the maintenance of roads and crap. Walmart isn’t going to gleefully cough up money, they raise their prices to try and pay for any roads they wish to be maintained, which would be almost none considering how many roads they’d have to keep up. There are way too many roads that need to be maintained/built for the private sector to handle. Nowadays roads are a necessity, and people wouldn’t be happy with someone trying to bring back dirt roads and crap. Also how would car crash damages be handled? From donations on people who use that roads? Yeah okay. How about lights? Who would control those? Does every light have its own owner or what? There’s a lot of problems with the private sector taking control of road maintenance.
And the private sector taking control of education is certainly funny. Colleges are already extremely expensive, if the private sector got a hold of all them, college prices would get hiked up. Yes private colleges often do really well, but everyone knows their expensive and many can’t afford them, which is why wayy less people go to private colleges than public ones. And ‘the church’ providing basic education and healthcare? Ha! You’re basically asking for a theocracy to establish a base, and for discrimination to run rampant. There are many different sects of christianity now, so if one sect got power over another, who is to say that they not offer education and health care to lesser sects they disagree with? What about people of other religions? Muslims would surely be targeted more often, and atheists would probably be shut out from educational services. LGBT people too would targeted. And most of the rich don’t care about the people less fortunate than them. are there some who do? yes of course, but most would gladly replace workers as soon as they dies, versus doing anything for them. Most employers are forced to give their workers health insurance, something i have no doubt most would get rid of if they could. This minimal state you envision would just lead to a plutocracy, and if the christians were able to get together, it would become a plutocracy/theocracy mix. That would certainly be more oppressive than the state we have now.
