None of the top six there are countries you would describe as having "lower taxes, fewer public services".
I.e. implying that lowering taxes and public services simply shifts the corruption to the "private sector" as if it's just shifting the problem around and is inescapable. Or that it leaves a gap to which "private sector corruption" can slide into.
To which I responded by saying that at least the [increase] in corruption can be avoided more easily if said corruption is in the private sector as opposed to in the government. So even if we're just shifting the corruption to the private sector, it's still better overall because we can more easily address/avoid it than we would be able to with a government. The point stands whether I am aware of the private-sector corruption or not, and also stands whether there are alternatives within the private sector to switch to because one can just choose to not participate (barring certain necessary industries, I guess)
There's this sliding scale ranging from "lower taxes, fewer public services" to "higher taxes, more public services". Really, anything on that spectrum is going to be workable.
Corruption is where sliding that scale towards "higher taxes" results in most of the additional money finding its way to the pockets of various bureaucrats and their friends, as opposed to being used to deliver services-as-promised.
