It's more like, conglomerates establish a bank, & once they do, odds are stacked in their favor. Every monetary injection via RRR cut (and maybe even every withdrawal via repo rate hike, though I'm yet to explore this), conglomerates benefit - over & above MSMEs & workers. BSP's fiat is their mana.

P.P.S. How much less? 100.08%/100.00016102385% = 0.99206508952. So the probability of being selected shrinks by 0.21% a year. By the end of 60 years your probability of being selected - little as it is - would have shrunk to 62% of the original (P = 0.00002173913). 11/10

P.S. Note that is an understatement. That the population growth rate in the PH is 0.8% a year, but the required sample size for a 2% margin will only grow by 0.00016102385% a year! That means as the pop'ln grows you have less & less chances of being selected per year. 10/10

So, if you get interviewed at least once in your entire electoral life, consider yourself the lucky one out of five Filipinos. Otherwise, that's just the consequence of statistics. 9/

So our formula gives us 1-(1-P)^9,360 = 0.18411386371.
That's roughly 18.5% - there is only less than 1 in 5 chances that you will be interviewed at least once for the rest of your electoral life, even if we assume there are 3 surveys a week. 8/

Do the same to compute the prob. of one being interviewed at least once in his entire life in all major surveys. Say there are at least 3 surveys per week from different firms. That's extreme. Say that one's electorally active life is 60 years. So that's 3x52x60=9,360 surveys. 7/

From here, we can get the probability that you were interviewed for at least one of the surveys. That is 1-(1-P)^192 = 0.00416525948, or 0.416525948% - less than half of a percent chance. 6/

What's the probability that you were not interviewed for at least once? To answer, we get the prob.that you are not interviewed in a survey. That's (1-P) = 0.99997826087. Now, we get the prob. that you are not interviewed in all 192 surveys. That's (1-P)^192 = 0.99583474052. 5/

Now, 2,500 / 115 million, gives you a probability P = 0.00002173913 of being selected. Suppose there's an average of 1 survey / quarter, & your active political life has spanned 30 years: you're 48 old, & you would have been qualified for a survey since 18. That's 192 surveys. 4/

For those curious, we can use the Yamane formula in this case: n = N / (1 + N * e^2). N is the population size, n is the sample size, and e is the level of precision (say 2%). So plugging in N = 115 million will give us n~2,500. 3/
