Nobody is asking to be carried by workshops alone, they are asking for workshops to be worth it.
Really seem to me like a substantial amount of people are asking for exactly this. Which is really silly IMO because trying to earn enough money to get by is a central part of the gameplay loop, like if you are sick of the things needed to make money in this game you might just be sick of the game period. Which I get we are all waiting on the feature to fill out.
You can still get workshops with incomes ranging from 200-300 a day.which I think is very reasonable.
There is however problems with workshops that relate to how goods are demanded and prosperity growth. The reason workshops are only strong in towns with higher prosperity is because demand for certain goods classed as luxuries is determined by towns being prosperous, it isnt a linear scale though, as after a certain amount of prosperity the demand for luxury good grows more quickly, which I think is cool it just need fine tuning.
Leather seems to have particular problems as the raw materials are in higher demand than the processed good especially late game, when generally prosperity should be higher.
So workshops are connected deeply into other systems and as such they are not simply "buffing them" but trying to get those system working togethers as they should.
Passive income is very strong, and given the lack of gold sinks it makes sense they are conservitive with it.
Take some simple math examples of how income effects wealth.
Say your total expenses are 9 a day
and your income is 10 a day from loot and bandits (averaged over a week, some day you make say 0 some days 30 )
10 - 9 = 1 profit a day
Over a 10 day period your wealth accumulated is 10
Now lets take the same example but add passive income
Expenses are 9 a day
you average income from loot and plunder is 10 a day
you also have a passive income from workshops of 5 a day
10+5 - 9 = 6 profit a day
Over a ten day period your wealth accumulated is 60
So even though your average income increased by only 50% your wealth accumulated inceased by 600%
There are very few sinks for wealth in this game, so very soon after going positive on daily expenses you move towards infinite money $$$$$$$$$$$$.
Place them right and workshops are really good you guys just suck I rest my case your honour.
