Actually Laissez Faire is really nice if you build SURE companies while with state capitalism, such as Liquour, cars, phones, airplanes etc and then switch to laissez faire and let capitalists just expand factories whenever there are unemployed people.
Imagine clicking "expand" button when playing with say Brazil or other bigger country with 8+ states and 8 factories in each and flooding 100k unemployed craftsman in each provinces because your factories are full and it takes time to lvl them up, while all your pops are mad rerolling to craftsmen cuz all rgos etc are full.
Another downside to state capitalism and subsidies is that it lowers your industrial score if you have a company and its on -, often when I delete such company my industrial score goes up, even if others are full so it's not from them being filled up with people. Another note - Laissez Faire gives +5% factory output + liberal/anarcholiberal parties almost always have full citizenship and that's what you want, especially as new world immigration magnet.
Oh god I love doing this,

Communist and socialist parties have full citizenship too. Anyways, I personally don't mind all that expand clicking, I've played as US till about 1900's when craftsmen are just storming all over the country and I had no problem expanding all of those factories constantly. I prefer it more than having to rely on some kind of AI that doesn't think properly. Plus, in Laissez Faire I can't control my industry, that's what I hate. State capitalism allows capitalists to do the job too, but also allows you to do some stuff. Sometimes I demolish a low-level factory in very craftsman-filled state just to replace it with a newly invented factory that is sure going to help me a lot in mid-late game, while capis will take ages to do it and they'll put it in some kind of lowly populated state that will have trouble filling all the workspots.
I'm sure Paradox will advance the interface you are upgrading your factories as much as they did in EU3 (merchants, buildings..).
Indeed that's true about community/socialist. However if you are playing a country that's in a troublesome area, fighting wars on few fronts, on sea and expanding factories every few minutes turns into an annoying chore.
Probably Interventionism is best solution..You can delete factories you don't like when u notice capitalists building them and at the same time capitalists expand factories for you. Tho I almost always go after 1880+ with Radical party if I'm playing as HM gov. (I switch to State Capitalism and then back after 1 year if capitalists are too stupid to build something useful)
Anyway enough of offtopic, hilarious stuff.
I actually think that Interventionism is the one that prevents capitalists from doing anything. State capitalism allows player and capitalists to have full control over the industry (build & expand factories). IMO state capitalism > all. It doesn't matter to me that Laissez-Faire has lower factory cost, with my millions of pounds in money reserves I can build any factory I want to without trouble, unless I'm playing VRRP, in which every few weeks you get a money draining event (most of them allow you to get a lot of prestige in return, like build Suez and Panama canals, that's how it should have been in the first place...).
This, Laissez Faire just needs a little spark and the engine will run.
