Please can you check my composition about education . Thanks everybody

THE educational process (исчисляемое существительное) iS impossible without special facilities( в вопросе facilities имеют значение скорее образовательных учреждений, а не вспомогательных средств обучения) which are essential aids in communicative teaching. In most welfare (welfare обычно сочетается со словом states)countries public schools ( public имеет разное значение в Англии и США, в Англии это частные школы - вы их имели виду?) and state universities are provided FOR by the government.
There are people favoring the idea that all expenditures on EDUCATION should be covered by the state. They claim that all people/EVERYONE who are/IS working and have profits have to pay taxes. Taxes are designed to make such aspectS of life as HEALTH CARE ( не надо переводить русские слова, такие, как медицинская помощь, надо знать, как это называется по-английски) , education and so on, accessible to the population of the country/everyone. Another argument in favor is that THE standard of living in VARIOUS regions of A country may vary ( OR: the standard may vary from region to region) greatly. Some regions are BETTER developed and there is almost NO unemployment ( UNEMPLOYMENT IS LOWER THERE) and salaries are higher than in less developed regions. Consequently, parents who live in richER regions of the country are able to amass more money for providing BETTER EDUCATION FOR THEIR CHILDREN. AS A result, SCHOOL students supported by more affluent ( well-off is used predicatevely, well-to-do is used attributively) parents will have a golden opportunity to study in well-endowed educational ESTABLISHMENTS (institution часто сочетается с mental и понимается как дурдом) . As for students who live in less prosperous regions, they may become victims of the depressing opportunity effect ( для компактности стоит избегать of-phrases, ставя определение-существительное в препозицию) because they will/may not have an opportunity to have A well-equipped classroom( не о classroom речь, а об учебных заведениях) .
There are opponents who consider/think that all educational facilities should be supplied by parents... They believe that THE government educational budget is very tight and THE money ALLOCATED to education(al purposes) is not sufficient for new and modern facilities.
As for me, I firmly believe that THE government must/SHOULD provide FREE education from KINDERGARTEN to UNIVERSITY SO THAT all studentS COULD enjoy equal opportunitIES. Parents, for their part, COULD donate money at will and to the extent possible(?)

They believe that government? that? educational budget is very tight...
... I firmly believe that government must provide??D???

... in order that every student could enjoy the equality of opportunities.

On the other hand, parentS may donate money at will and to the
extent ???possible???

В третьем предложении вместо is стоит in. Если в России образование действительно станет абсолютно платным, то мы вернемся в Средневековье по уровню грамотности, так что суть статьи поддерживаю.

Educational process iS impossible

There are THE people favoring the idea that

welfare - если не ошибаюсь, только существительное и не может быть определением в превосх. степени.

such aspectS of life

medical CARE\ AID\TREATMENT

as THE medical treatment, THE education ЗДЕСЬ ЛУЧШЕ ПРОДОЛЖИТЬ: РАЗВИТИЕ НАУКИ, ОБОРОНА and SO ON

and so on, СВЯЗАНО РЕЗКОВАТО ПРЕДЛАГАЮ : Новым предложением THE medical treatment and THE education should be accessible to ALL SITIZENS OF THE STATE

THE less developed regions

affordable лучше подходит, чем accessible

Another argument FOR of this statement is that standardS of living ИЛИ УЖ ТОГДА - THE STANDARD

in DIFFERENT regions

there isn't almost unemployment - ALMOST -НЕ НА МЕСТЕ there is NEARLY NOT unemployment

Consequently, THE parents who live in THE rich regions to

to COLLECT more money for providing THE facilities.

AS THE result SCHOOL students supported by better-off parents !!!have !!!A BETTER opportunity to study in well-endowed educational institutions. зДЕСЬ Я НЕ СОГЛАСНА С ИДЕЕЙ. НА ПЛАТНЫЕ МЕТА В ВУЗАХ - ОГРОМНЫЙ КОНКУРС, А НА БЮДЖЕТ ПОПАДАЮТ КАК РАЗ -ТАКИ ТЕ, КТО ИЗ СКРОМНЫХ ПО ДОСТАТКУ СЕМЕЙ, НО УМЕЕТ РАБОТАТЬ.

THE standard of living in regions of one country may vary greatly
and, moreover, salaries are higher than - запятые
They believe that government that educational budget is very tight -??что Вы имели в виду? ?
As for me, I firmly believe that government must PROVIDE all educational
in order to all student enjoy equality of opportunity - SO all students could enjoy
On the other hand, parentS may donate
On the other hand, parent may donate money at will and to the extent possible. -?что Вы имели в виду? :D
