Ok, But lets see how many they can afford to build
Not many:
Sukhoi Su-35S: 128 (6 test and preproduction, and 122 serial aircraft)
Sukhoi Su-57: 12 (10 test and 2 serials) as of 2020
Russia's Su-57 Stealth Fighter Has Problems: Engines, Oil, and Weak Adversaries
All the cards are stacked against the Su-57 — the price of oil is low, it’s engines are no better than its predecessors, and the current airframes it would replace are doing just fine.

Less Money, More Problems
Russia depends on oil and gas for revenue. If these energy exports would slow to a trickle — or when the price for these exports is low, less money flows into Russian state coffers.
The disagreement between Saudi Arabia and Russian to put a price floor under crude prices by cutting oil production has caused the price of oil to fall dramatically. Increased Saudi production has flooded the market with a glut of cheap Saudi Arabian crude, which is designed to undercut Russian exports of the black gold.
Saudi Arabia’s consolidation of its global market share is bad news for the Su-57, and really all Russian military acquisitions, which will likely be hit hard in the future. There will almost certainly be less money for ambitions and expensive projects.
Old Engines
There is another fundamental problem with the Su-57 — its engines are essentially the same as those of the aircraft it is designed to replace, the Su-35S.
Although the Su-57 was intended to sport the more powerful and efficient Izdeliye 30 engines, most — if not all — prototypes and production models have been equipped with the Al-41 engines used on the Su-35S. There have been reported problems with the new Izdeliye 30 engines, related to reliability and quality control.
Additionally, both the Al-41 and the Izdeliye 30 are essentially higher performance variations of the Al-31 engines. What the Su-57 program need are completely new engines designs — no easy feat.
The Performance Problem
Thus while the Kremlin’s Su-57 does have a better (more reduced) radar cross-section than the Su-35S, the latter airframe is fairly advanced for a fourth-generation fighter, and has proved itself more than capable where it has been deployed, particularly in Syria.
In 2018, India withdrew from the planned joint Russian-Indian Su-57 development. The Indians were evidently not convinced that the stealth and flight characteristics could provide exactly what they were looking for — another financial blow to the program.
Quite frankly, there just isn’t a pressing need for the Su-57 in the conflicts in which Russia is currently involved in. The Su-35S and other aircraft are proven platforms that can do the job, without an expensive and perhaps ineffectual stealth aircraft.

Of course, since they don't have what is, for now, the world's reserve currency like we do, they can't borrow like mad like we do.
Someone relatively well known in the investment or financial pundit community recently said, tongue in cheek, “Why bother to collect taxes at all?”
Why he said that:
2020 Federal tax receipts – $2.13 trillion
2020 Federal spending –
$6.55 trillion
“COVID” relief bill – $1.9 trillion - nearly the entire tax receipts last year.
2020
interest paid on national debt: $522,767,299,265.34... $522.8 BILLION which is about 1/4 of Federal tax receipts.
And that is at the incredibly low interest rates being artificially held there because, despite the MASSIVE DEBT-based SPECULATION that causes which leads to INSANELY overinflated markets and the INEVITABLE crashes that eventually follow, the central banks worldwide have TRAPPED THEMSELVES in a situation where if they raise rates, the entire
debt-levitated circus tent comes crashing down.
In addition, in our case, if rates were allowed to rise to historic norms via natural market forces, multiply that annual interest payment on the national debt by many times:
