Proposing that we should continue to throw more money at infrastructure, before diagnosing and fixing the problems that are causing that inefficiency (at which point, sure, double the infra budget - as long as we're getting good value, the absolute amount can go up as far as I'm concerned), is straight-up malicious.
The only people who make the argument to keep increasing the infrastructure budget before fixing the problems are those generically interested in throwing more money and power at the government, not those actually concerned about infrastructure (who will seek to fix the problem first).
