If it were not for stupid trade laws, where other powers can 'trade' 1 CF for 8 of my hard earned oil or rubber ... that I can't block [serious swearing], yeah, I can see not going past Synthetic 1; democracy's don't have it easy, they don't get to use Closed Economy [more swearing] .
So I think I've a possible work-around : pick a faction that currently has a lot of oil/rubber, and has 2+ majors; for you to go to war with . An active war apparently blocks 'trade' of captured resources ... stomp all over your enemies, and LEAVE the 1 surviving Major JUST short of capitulation; and little hope of recovery, do not let the Peace {pieces??} Treaty happen until the equipment you need for the next war IS ON THE MAP !!! Then kill off the wounded major for the Pieces Treaty, re-organize, and start WW3 .
