A 1,000 dollar Powermatic tablesaw is functionally immortal. It will always be worth 1,000 dollars, so you buy it and use it until you don't need it, then sell it to someone else for what you paid for it.
When I last had a big shop full of stuff at home, my machine and cost list was...
1) Used Powermatic 66 table saw ($1000)
2) A used Woodmaster 18" planer ($1200)
3) A router table I spec'd to my local machine shop which attached as a replacement wing on the Powermatic 66 to share its fence ($500)
4) A used Grizzly 8" jointer ($500)
5) An "American Sawmill Machinery Unipoint" miter saw from the 1950s ($300) (^)
6) A General International mortiser ($1000)
7) Couple of routers, one big one and one 1.5hp one ($600)
(^) This was the best machine I ever had, sold it for $500 when I was done with it. Imagine a miter saw that's all cast iron rather than aluminum and plastic that can cut invisible miter joints.
So not 8,000, more like 4,000-5,000 if you buy a bunch of used stuff. I can't think of a reason to buy new woodworking machines, when there are so many used machines floating around craigslist or exfactory on any given day.
Any of these machines could be lesser/smaller alternatives, which would not limit the quality of output but rather just limit the size of raw materials you could use and perhaps slightly increase waste. For instance there's no reason you can't cut small pieces on a small table saw and break down 4x8 sheets of ply with a Skil saw. The only thing the big cast iron saw gives you is the ability to skip the Skil saw and minimize waste, really.
Similarly, anything that I did on my custom built router table (or a shaper) could be done with a hand router and jigs, it'll just take more time to build the jigs. About 80% of woodworking is learning 'clever tricks' and learning how to conceptualize jigs to accomplish repetitive tasks accurately. Machines can do it for money but your brain can do it for cheap, just a matter of learning how.

Doesn't have a shaper but he has raised panels at the end of the day ;).
I mean, I've stumbled across guys that make a living building wooden windows, doors, and cabinet doors with a small army of used Powermatic 2A tenoners (no longer being made, you can only buy them used). They're not required to build a cabinet door, though, they just reduce it to unskilled labor simplicity.
