Obviously, you don't understand models.
The models are not wrong, they've just been recalculated to factor in the positive effects of social distancing and other measures to stop the spread of the disease and your inability to recognize that is not even inspiring.
FICA tax revenues are a very basic model:
Total FICA Revenues = # of Workers * Wages * FICA Tax
From our 6th Grade Math, we know that if we change any of the variables --
# of Workers or Wages or FICA Tax -- we change the output.
If we increase the # of Workers, then
Total FICA Revenues increase.
If we increase the FICA tax, then
Total FICA Revenues increase.
If we decrease any of the variables,
Total FICA Revenues decrease.
If we decrease some variables and increase others, we get a mixed result.
You did complete the 6th Grade, didn't you?
I just don't want to talk over your head.
Population models are just like that, except the math is a little different because of the use of summations and square root regressions and such.
A very valid assumption is that it's "business as usual" and if one person can infect 6 people in a given day, then you can see how it spreads, right?
1 person infects 6 who each infect 6 people who each infect 6 people.
How many people is that?
That's 1 + 6 + 36 + 216 = 259 people infected.
Recalculate for 1,800 carriers of COVID-19:
1,800 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 503,884,800
That's how many people are infected in 7 days: 500 Million
If you alter the variables by reducing the number of contacts per day to just 1 using social distancing and shut-downs and such so that one carrier only infects one other person then you significantly reduce the number of people infected to just 12,600 people which is a helluva lot less than 500 Million.
That's just a simple explanation. If you want to do it the correct way, then assume something like 600 carriers who infect 2 people per day:
Day 1: (600 * 2) + 600 = 1,800 infected
Day 2: (600 * 2) + (600 * 2) + 1,200 = 3,600 infected
The original 600 carriers are still infecting people.
Day 3: (600 * 2) + (600 * 2) + (600 * 2) + 1,800 = 5,400
Day 4: 16,200 infected
Day 5: 48,600 infected
Day 6: 145,800 infected
Day 7: 437,400 infected
Day 9: 1,312,200 infected
Day 10: 3,936,600 infected
Day 11 : 11,809,800 infected
Day 12: 35,429,400 infected
If your model assumed weeks instead of days, then at the end of 12 weeks there'd be 35.4 Million infected. Obviously, I didn't account for dead people and those hospitalized no longer spreading the disease, but a real model would.
