And here is GDP in 2010 dollars: https://data.worldbank.org/indicator/NY.GDP.PCAP.KD?location...
State and local governments went from spending 10% of $23,000 per person to 15% of $55,000 per person. Per-person state and local spending went up by a factor of 3.5, even after adjusted for inflation.
With respect to public infrastructure specifically, there has been no austerity. For example, here is a graph of NYC subway ridership from 1970 to 2014: https://i0.wp.com/plot.ly/~millerstephen/4.png?w=773&crop=0%.... Subway ridership is up 75% since 1980. The capital budget during the 1980s averaged $3.4 billion annually in 2020 dollars: https://wagner.nyu.edu/files/faculty/publications/rescue.pdf (fig. 5). The 2015-2019 capital program (5 years) averaged about $6.5 billion 2020 dollars. So a 90% increase in capital spending for a 75% increase in ridership. Punchline: MTA is so massively wasteful, that wasn't enough. The system deteriorated the whole time leading to catastrophic failure in the last few years.
The London transit system, by contrast, spends about $3.2 billion in capital expenditures to run a system that is very similar in terms of age, size, etc: http://content.tfl.gov.uk/tfl-budget-2019-20.pdf. Despite spending half as much money, London has been able to significantly grow the network while keeping maintenance current and maintaining on-time performance.
Honestly, invocations of "starve the beast" and "austerity" are nothing more than gaslighting. It's a cop-out for why our public services are so shitty, even though we spend vastly more on them than we used to spend.
Obviously the capital spending boost that is happening right will only be reflected in future ridership.

Inefficiencies or corruption when building new things?
Pension benefits for an aging workforce?
Pure incompetence at the top or pure incompetence at the bottom of the org chart?
Transit capital projects in the USA, for instance, are typically delayed for many years by lawsuits over environment laws, etc. For instance, near the nation’s capital: https://bethesdamagazine.com/bethesda-beat/transportation/pu...

And on the other hand, there’s straight up corruption and fraud. https://www.nytimes.com/2020/02/03/nyregion/cuomo-andy-byfor...

Just because the spend per rider increased over that time doesn't mean the system is getting what it needs though. A newer system will usually function better than a starved system years later naturally because of deferred maintenance and other aging infrastructure ailments even if the per rider numbers have increased. Comparing it just on the per rider spend assumes that the earlier number is enough.
Though I suppose you would have to look at the state of thr system in the 1980s. NYC may have had more deferred maintenance.
(The local share of property tax was not defined in Prop 13; this is strictly how the Democrats in power chose to implement Prop 13.)
