The difficulty of getting people to vote for tax rises is a good justification for privatization. This difficulty isn't some uniquely right wing thing. The Democrats and Labour don't campaign on general tax rises either. At most, the left are willing to campaign on "tax rises for people who aren't you". That's because any party that wants to raise taxes on the majority loses.

So, governments of any color have to work with that as a constraint. Given that nobody has worked out how to convince everyone to accept big increases to their tax bills, you can either pay for new expenditures with borrowing or with cuts elsewhere. Sometimes cutting elsewhere is also hard, so either:

1. Everything gets put on the credit card. This ends badly.

2. Stuff is privatized. This yields an immediate cash influx, and voters are usually happy with the results which is why very few privatizations have been rolled back. The reason is that outside of very left wing spaces most people trust private companies on pricing much more than governments. Private companies run special offers, sales, sometimes cut prices even in the face of inflation and can be visibly seen competing on price. Government owned organizations never do this.

It's also (quietly) popular with governments on both left and right for another reason - it means they have less stuff to manage and less stuff that can blow up. If there's a problem with a privatized industry they can just tell you to switch to a competitor instead of needing to campaign on it and promise to do better.

Natural monopolies do exist and sometimes governments just have to bite the bullet and run such things themselves. But there's a lot of room to debate what is and isn't a natural monopoly.

They should try it. We desp3rately need to move the Overton window on this.

Tax is good. We need more of it. A screamingly obvious fact. Give us a chance, please, to vote for it.
