And in Revolutions capitalists building stuff ONLY if goverment type is right which means: Interventionism [you can still build roads by yourself if you want] or Leisse-Faire (whatever) [capitalist building factories/roads and you can ONLY expand forts and naval bases] <- extremly annoying form of gov.
Capitalists are useless when country is running on State Capitalism or Planned Economy [or you playing basic Victoria

] . And to make capitalist work you need to lower taxes for the rich to like 0-5% (but it all depends on a country you play - e.g. with Japan it takes blink of the eye for Cap to gather enough ca$h, with smaller countries like Persia it takes forever).
About revolts and reactionary. What is you Pluralism level? With high pluralism [lets say 50%+] and Monarchy things getting out of hand very quickly. At some stage turning into Democracy or Const. Monarchy is the only way, unless of course you enjoying red-hot revolt map display.

Because Japan "running" on farmers and labourers very much the only way is Suffrage. If you selected Right to Ban one tip: Do not actually ban parties - banning parties increasing militancy greatly, for liberals in particular. Right to Ban option is only useful when in Revolutions you running on Inter/Leiss-F goverment, but AI doing everything to NOT build factories or building/expanding not needed crap - Glass, Winery an so on, or building them where is 1 non-national POP

. Then you Pausing game, selecting some Socialist/Communist party for a paused-moment, building/expanding factories you want, converting non-national POPs (Full Citizenship), and returning to old goverment when you done. Cheating perhaps, but it is only way to keep up with cheating AI.
Have fun with Vic but buy Ricky. Well spend money!
