Privatising the power cables going to people's homes is a dumb move - you won't get the benefits of the free market, as there's no competition between suppliers.
But once the cables are in the ground, competition between multiple power suppliers might be possible - so long as customers can compare prices and switch suppliers easily; and the power plants aren't incentivised to cut long-term investments and imperil the country's energy security.
In practice almost every privatization is simply an exchange where the new owner pays the government $x to help solve its "debt problem" (because the government may one day be rendered insolvent by running out of the cash it it prints).
Then, the public gets soaked for $nx where n is usually at least > 2 and the government officials behind the privatization get some really lucrative jobs and speaking engagements after they leave office.
You don't get that money for nothing. You're selling part of the nation's infrastructure, that was paid for by taxpayers, to now be exploited for profit. The taxpayers end up paying twice.
It's better to keep the essential infrastructure nationalised, and allow private parties to use it.
Maybe. If it's taxpayer funded infrastructure, it doesn't perpetuate itself by self determination. It must be maintained with more tax dollars.
Assuming the cost is equal whether it's privatized vs. state-owned, then it all boils down to a matter of ideological preference. Some object to others making a profit off of a public good. There may or may not be merit to those arguments, but they're completely orthogonal to whether or not there are costs associated with their maintenance, because there always are.
The taxpayers always end up paying twice.
Raises is a very positive sounding word.
Would it be better to couch that sentiment in terms of who's getting shafted (it extracts money from) or who's getting rich (it redirects wealth to)?
The closer that the government is to me, I more that I can control it (albeit with much frustration sometimes). But, private ownership, I can't control.
Is there conclusive evidence that privatization is worse?
It seems like an age old question. That there are positives and negatives. It's also politically expedient as it raises money.
