So I spent some time recently (putting off important things) reading the thoughts and opinions of neoliberals to get a sense of what the ideological competition is. Because center-leaning neoliberals are the only intellectual group worth reading and taking seriously, American Republicans are completely gone.
Neoliberals try really hard to derail discussions about inequality. There's actually a variance from what I can tell in people who support it, you have basically conservative anti-regulation sorts and anti-socialist social democrat kinda guys, but one thing they all agree on is that people like Corbyn and Sanders are radicals, ideologues who are extreme on the economic spectrum. They quote
Thatcher, and well, they give a pretty simple argument about why they think income inequality isn't a problem: because income inequality, just like the Laffer curve, are not economically incorrect in principal, so by attacking it socialists are dumb.
Basically their argument is exactly what Thatcher says in the video: income inequality doesn't mean anything in itself, and other metrics are more accurate. Which is actually an alright criticism: income inequality doesn't, on principal, mean things are worse, it's conceivable that the gap could widen yet quality of life improve for all people, they also seem to love
consumption inequality as a metric, claiming consumption inequality is static (while basically ignoring that consumption is increasingly funded by debt..). Just like the Laffer curve is sound economics on principal: at 0% and 100% tax rate, it's reasonable to assume no tax will be collected, and if there's continuity that means there will be a tax rate that returns the largest revenue. They think then that redistributive policies create market inefficiencies.
The problem is, their debates about inequality are used the same way Republicans use the Laffer curve: as a matter of principal and without applying it to, you know, actual cases. They seem to ignore super inconvenient studies like how
even the IMF, not exactly a leftie source, says that basically income inequality inversely correlates to growth and redistribution has little to no effect on growth.
At most, neoliberals seem to admit that, when there's income inequality, people with more income have more undue influence on politics, this undue influence is anti-democratic and leads to populism (aka Trump, Sanders, the real evils). They seem generally accepting of social welfare just to, essentially, keep the proles happy so they don't elect someone like Sanders.
In other words, to be a neoliberal, you need to accept that there exists an argument that's true on premise but don't read any of the studies testing that hypothesis, because basically every study done on income inequality correlates it with things we all don't want.
